@G.T
I tend to agree with what you say, but your wrong about a couple of things like the sub-auto's, and you failed to mention some of the most effective weapons in the game!
Besides that, a guns is only at its most effective when used in its correct role. So saying this gun or that gun is bad based purely on the in game stats is wrong. Battlefield situations and player skill will ultimately define the practicality of any weapon and its effectiveness.
I'm on my second tour now (equivalent to level 86 of 550), and for my first tour I decided to level up most of the weapons in the game (you get a lot of xp for doing this BTW), and I wanted to get as many weapons upto ACOG status as possible so I could see what was good and what was not so good, and in what situations. The weapons I have listed below are what I believe to be the 'best-of-the-best' in the game.
First of all the LMG's:
The SPD should be the weapon of choice for anyone at level 4 (it is available in create a class). Its high rate of fire and damage (combined with stopping-power) make it a very effective weapon. I've never used the grip, and I can consistently drop any target at long range with just the RDS Reflex scope. Of course the grip improves long-distance accuracy, but I've never seen a situation arise where I would need to use it regularly.
Next, the M60 is BRUTAL! pure and simple. Combine this weapon with stopping power, and all those juggernaut whores will be crying like babies - its unstoppable! it litterally only takes a gentle squeze of the trigger to register the kill. There are a couple of peculiarities that you must adjust to with this weapon though. Firstly, the iron sight is a little intimidating, and can put off all but the faint hearted (though accuracy is superb), and secondly, the rate of fire is not stellar, but if you can overcome both of these faults, you will have one of the most powerful gun in the game!
Secondly, the SMGs:
There are a couple of guns in the SMG class you should use as a matter of course they are:
The AK-74u is a very under-rated gun. This is my preferred CQC weapon along with the SPD. A high fire rate and AK-47 like damage, with less recoil make this the only AK of note in the game. Its feels light in your hands too. Some guns like the LMGs and the assault rifles feel heavy, but this gun is just right and on most maps its a dream to use. Honestly, this gun is much better than the stats say it is, and obviously can be looked over by those that rate guns only by that method. Very effective at all ranges up to medium-to-long range, aquaint yourself with this gun for maximum effect (don't forget the RDS Reflex scope!).
Next up is the P90. This is a great gun, and probably one of the most effective in the whole game! Link it up with double tap, and you will have an awesome gun with a ridiculously high rate of fire. Very effective at close and medium range, and descent at medium-to-long range, this gun is in a class of its own!
Onto the Assault rifles now:
I don't usually use the ACOG scope (its requires little skill to use), but mated with the already sublime M16 makes it a portable sniping platform that some of the sniping rifles wish they were! With stopping power, the M16 can drop anyone with a single-three round burst to the chest/head area. To my knowledge, no other weapon (except snipers of course) can do that with any regularity. This weapon seems super-powerful compared to the rest of the guns in the game, but then if its there, use it! The only down side to this weapon is the semi-auto fire rate, that can make CQC really hairy. Best used for meduim and medium-to-long range attacks, this gun is a treasure! Oh, did I forget to mention that there is virtually now recoil on this weapon? Not a sniff, nadda, zilch! 👍
Now the M14. This is another Assault rifle/sniper rifle combination that can be a killer in the right hands. Its single fire rate though, can deter even the most hardy of shooters. Personally I love this weapon. Its VERY powerful, accurate, and can double up as a sniper rifle with the ACOG, the only downside I've noticed is the muzzle drift during semi-auto fire - it is extreme compared to other guns. This gun is the gun of advanced shooters, but is still accessible enough for those who would like to give it a try. On a side note. If I was a sniper, I'd start off with this gun and the R700 (using the overkill perk), and ditch the R700 in field for a sub-auto (you have to start with a sniper rifle, or you don't get the Ghillie suit).
I have no opinion on the sniper rifles as I have never used them, I do like the .50cal Barrett's, even if I have never fired it in anger!
GUNS TO AVOID
The M4 looks like an attractive proposition when first encountered, but in reality, its a weak (MP5 weak) gun that has no redeeming features. Compared to the M16 that it seems to be based upon, the M4 has no power, worse accuracy, and worse range and recoil. Its only saving grace is it fully-automatic rate of fire. In many fire fights I have found myself out of luck with this gun in my hand - it has very poor stopping power, even at close range. using this gun against a juggernaut whore is an exercise in futility. If a gun can be almost negated by a perk, then its no use whatsoever on the battlefield. Avoid!
As an iconic symbol of resistance the AK-47 has no equal. On the digital battlefield though, its slow fire rate, and dreadful muzzle drift make this a weapon to resist using! don't get me wrong, the AK-47 is a powerful gun, with descent accuracy and good stopping power, its just seems a little old school. Combined with the RDS Reflex and the ACOG, the gun gets a new lease of life, but ultimately as your skills improve, and your rank rises, this gun will get used less and less.
The Desert Eagle is a formidable weapon, but its high stopping power is offset by the ridiculous recoil each time it is fired. Compared with the pistols, this gun is too overpowered! I can usually register kills with them, but this guns recoil makes it an unfriendly gun to use. The gold Desert Eagle though, looks the part...
As for perks I personally use 3 flashes, stopping power, and steady aim. Its the same for all weapons. I did try using 3 frags, but the fact that your grenades can bounce off other guys on your team, and you never know when someone on your team will step in front of you, I judged its safer to be blind than dead (occasionally I will bounce a nade off the wrong wall too, and it will land back at my feet!)
I'm in the process of writing up a battlefield survival guide that is aimed at those that are new to FPSs or those at lower ranks. It will cover weapons, tactics, and maps. When Its ready, I'll post it here.
Great game tonight, although it didn't go very well for me, I seemed to always be on the wrong place during the match.
But as soon as I unlock it again I will use 3 Grenades, since throwing cooked ones at a Domination flag being captured guarantees a kill. Perk 2 (or 3?) I use the extra damage. Maybe I should try another one to see if it's not the best, but I seem to play well enough as it is so I think I'll leave it. Perk 3 (or 2?) I use dropping a grenade. I tend to get more kills with the Last Stand perk, but I wasted time using that ever since I've been playing Domination. The more time you have running around the better, so the grenades it is.
Please accept asap, guys. I want to shoot your brainses out.
