Snaphook I agree that when it goes live it needs a full wipe. So all those guys in their IS4's and KV3's will start over again.
To me the biggest problem is in the match making side.
You put a tier 3 tank in with tier 5's, 6's, and 7's guess what happens to the poor 3? Yep he gets slaughtered.
Hit a KV3 13 times in SU-76, 2 did damage, the rest just bounced. Then he finally turns his turret, single shot, poof, I'm toast.
Also rather than banning people for team killing (see a lot of that at times)
They need to do Killshooter like HT figured out.
You shoot someone on your team, you take the damage.
Tanks start in a big pile, and if someone thinks you cut them off, they'll track ya for kicks.
You turn and shoot them back, are unlucky enough to kill them, and your smacked with a TK ban.
Last I think they should double the size of the maps. Then increase "Visual" only sight range.
So if your scoped in on an open field at a half a mile, you'll see a tank move across your view.
But if someone is stationary, hiding behind tree's, then you won't see them.
I think that would slow the gameplay down just enough to give people a chance to communicate, and work together more.
