Maybe reduce their health like before the patch.
Currently you need 2 shoot with from the Zis.
And Guards take maybe to much time for kill him.
Hell no. If they do that then 222 will be " shit that no one use again "
Like I said, 222 just need the gun price up a bit that's all.
I saw a players spam 3 sniper than use Guards surround sniper to defend them. 2 of my 222 try to take them out from far away got fucked.
So, in conclusion: 222 right now is fine, you may want to increase the upgun price a bit but Don't even nef this shit cause Flame halftrack is tier 3 now.
