i'm pritty bad at fast-paced/small-map shooters like this game, so i been playing only snipers for the most times. and snipers in this game don't tend to get a high score because of the power sprinting and killcam(so using a silencer seems to be pointless), though they do tend to get a good k/d rate.
at this rate, lvl 39 seems soooooooo far away if i continue to play only a few hours a week. i need a new carrot.....
or maybe i should gather some friends and go the "boosting" way?

go boosting?

Try a hardcoe map so you can avoid your entire "killcam" argument. Or move to a different location that's nearby and snipe from there. It is easier to get kills running and gunning... but it isn't difficult to snipe. hardcoe is one-shot one-kill, by the way. Cheating will get you banned. So I hope you mean "running in a squad with friends" when you say "boosting." Not the boosting your stats boosting.

when i say boosting i mean exploiting holes in the game's rules(CTF mode to be precise) to gain huge xp very easily in a short time.

Make the most of the double xp weekend, and don't play sniper.

DON'T BOOST!!! It's unfair!
Go to a server with the "Pro" modifier. It's a sniper's heaven - no killcam, one hit kill snipers.

That's cheating and you'll inevitably have your stats reset.

Honestly leveling up is retarded, you should do whatever you can to get XP the fastest. I hated having to level to unlock weapons, I'd rather a button be there to just "unlock all"

this "double xp weekend" has attracted too many cheaters for me to bear. and i always get spanked badly playing any roles other than sniper. guess i'll never get used to the pace of mp (just like i never managed to keep up with cod's mp)
That's cheating and you'll inevitably have your stats reset.
and that's why i never did it before.

though i really liked the pro servers, the lack of hud is a big show stopper for me. i wonder if there is a way to just turn off the killcam on a standard ranked server.
