I think the armour buff was good and the unit is in an good spot right now. If there is to be another change, it will be seen after the patch release.
For now, this thread is completely pointless and the suggestion quite bad since the KV2 is already quite OP since its shell speed was increased.
Again with this oversimplistic 'everything is power level' approach. That's not how making a game works.
I can understand the people who think the Brummbar's current implementation is a good design. I disagree with them, but I understand.
But making something badly designed deliberately as a nerf? That's just absurd.
Is 2 shooting full health squads regardless of squad size and spacing balanced?
I refer you back to the rest of that post. If manual targeting is overpowered, then it needs toning down.
My entire argument is the Brummbar shouldn't have this massive power spike when you manually target it. The difference between its autofire and attack ground performance should be comparable to other AI tanks.
