Well, after playing for a few hours, I'm really enjoying it although I'd say the other things that bother me are:
Some awful textures although they are probably placeholder/temporary
CTD problems, but they'll get fixed soon I'd imagine
Lag kills this game really badly, I know it'll get sorted but it handles it poorly
FoV is too narrow/small, game could use a fov option from about 60 - 90 with a slider.
Fire rate seems a bit too high, you can really pop shots off very fast.
The dip on sniper shots and rockets is a bit too steep (sniper shots are worse though).
Default sniper scope is a bit naff
Too many things to go through when getting into game (logging in, fetching data etc)
I find crouched aim a bit too wide spread
No ability to go into prone
Can be shot and badly hurt/killed when floating down in your parachute
You can spawn camp people
Health is slightly too low, too easy to die from random fire
Other than that, the game is very fun, even though I had major trouble figuring out who was on my team and who was on the opposition.
