I only got to play it for the first 2 days, i didnt see any lag at all, but it does make me host virtually everytime. I was really impressed with the game tbh, i didnt think it was going to be any good but i was pleasantly surprised. I like the Support class, you actually get rewarded for being part of a team rather than Mr Solo. The only thing that is ruining it is the other people playing it, like the people who play HQ's and Domination and never get a capture. Just go play TDM and hide in a corner.
Long range silenced weapons damage is a bit rediculous as well, it doesnt seem to affect accuracy or range putting a silencer on, but it takes about 10x the amount of bullets from range.
