Overall i like the patch, game seems to run a little smoother at the start of a level but i still get some hangs that normally result in me dieing at least once without a chance to defend myself (i have 1 gig of RAM), so still not perfect.
On the balance issues, i am getting killed a lot more by snipers now, not sure if this is just a as the class had been improved and the use of it will fall back to mormal levels soon (ie i think more people are playing sniper post 1.2), either way it doesnt ruin the game and they did need improving.
C4 issues doens bother me, infact after having aquick go with c4 when i rarly use it i got several kills including a really good tank kill by stick two to his side while he was trying to cap a flag, jumped to prone over a sand wall just .5m from him blew it and survied, c4 is still a fair weapon for what it is.
The jets and hellis, now the missiles are more accurate when locked it is much more difficult but also much more exciting, now you have to chaff as soon as you hear the locking on tone before the missile warning and hit the deck, afterburners a do some mad turns, more challenging and more balanced. The hellis were overkill before and again needed to be toned down, im not sure if they went too far with this, time will tell but it is better than before.
The AWP seems like a nice gun, didnt bother with the P90 as i heard bad things.
The accuarcy changes for the guns are fine aswell for me, no biggie.
So again i tihnk the game is all the better for 1.2.
