GT5 v1.0 ==> v2.09 505pp was the name of the game for many, as we got accustomed to this pp, and the cars that we liked to drive.
GT5 v2.10 ===> preserve your rage, and do not! host, or join "505" as this is no longer the same 505 as was above. Find or make new pp, new rules, redisover cars, perhaps rediscover GT300 / F1 class, as I'm, so doing now. I'm done with online "Road cars" racing, until GT6 on PS4 is out.
Take your track knowledge earned from the time we spent at 505, and try F1 no aids on it, you will be pleasantly surprised at the relaxed sensation. PD did something to make road cars on RS tires handle worse than before, but they did the right thing. They want people to drive different cars that are offered in game, and to try other tires than just RS. Kudos to them, but change yourself in the process. I like the dynamics induced in 2.10, because it was beggining to feel lame that all 505 cars seemed to travel in the same speed in a straight line. It's more dynamic now. Don't race LFA limited engine, with a Toyota Supra that has less limiter, it's no wonder they dominate now.
I'm for this change, but it came a bit late in the game, no matter, good things are coming soon, PS4, GT6, we're gonna be spoiled with those graphics and sounds. AMD Bulldozer technology, easier developing, and easier patching and updates! Kaz , PD, do you read GTPlanet forums? in case, cheers and bless you guys.
