I honestly don't think the AVRE is that bad, and it doesn't have as much health as OP was talking about. People are overreacting a bit to this. The AVRE operates just like the sturmtiger. Same AOE, same dmg, however AVRE has a rotating turret but a bit shorter range and automatic reload, I would just say make the reload longer or decrease the AOE, not nerf it into oblivion.
Oh that's is interesting because I see the same people that were defending SturmTiger now saying AVRE is OP. Hmm that's rather ironic.
I don't say BTW that ST or AVRE are fine. Quite the opposite. I just wanted to point out double standards and bias when comes to balance.
