The reason I moaned about it was the way it has made using online to find good racing much harder. We now have to search through significantly higher volumes of rooms due to the high overall % of glitch rooms. Then when you do get into a room they seem substantially more prone to disconnections than pre-glitch.
Simple fact of it is that is you are using this glitch to further your own gameplay you are adding frustration to users who like to race [in the traditional sense] online.
I have not noticed the disconect issue.
As for the massive number of glitch roomes, there is always the option to actually search for a track you would like (and if PD did online right, search for all EXCEPT a group of tracks).
Simply put that means by using this glitch you are directly and negatively consequencing other users.
No it means you are indirectly inconveniencing others at worst. Just like all those guys who like NASCAR rooms (that I don't like) just like all the DRIFT rooms (That I don't like) like all the FREE RUN only rooms (that I don't like) just like everyone else that does things I don't want to be a part of... you don't suggest I get angry at them for making rooms like that do you? Just so happens this is what everyone likes right now.
That's called online...
Anyone who has ever lived in a big city knows that that comes part and parcel with the benefits of a large community: sometimes the community doesn't do what you want to do.
When it's good, it's great: A huge number of widely varied rooms with a lot of options for you.
When it's not great it's not great.
That's the balance of depending on online community for your fun.
How about you look to the source of the problem instead of the symptom for your unhappiness?
PD
1: People wouldn't be doing this nearly as much if GT was setup to be fun with a reasonable progression. Very few people pay $60 to then go spend time drivnig circles to cut short a GOOD TIME. The problem is so many people aren't having a good time they do this instead. Who's fault is that?
2: Online implimentation sucks. While a nice luxury would be "search for all tracks excluding -" which would be helpful almost anytime (I don't want to race NASCAR so if I could just exclude Daytona without limiting my search to only one track, that woudl be a huge hit - same for if I don't want to race Eiger etc) at the VERY LEAST matchmaking lobbies would solve this problem.
3: Not enough offline content. GT5 has put a large amount of it's eggs in the online basket by simple virtue of not having enough offline content. You are a victim of that yourself, that is why you find this problem as irritating as you do.
If PD had done some decent online, user created rooms would be where the glitching goes on and you could just jump into a hopper and go - think like CoD works online - you specify game type, game matches you with some other people.
In short, most of the people glitching have as much or more of a legit reason to do it than you do - they are being inconvenienced FAR more than you: They have bought a game that has a broken progression scheme and this is the solution to it.
The volume of people doing this clearly speaks to this not just being an "imature minority" issue... when the majority acts in the same way, there is probably a reason... sorry you feel offput... so do most GT5 owners.
