I don't think tank balance is going to be related to PS3 limitations but it's definitely a separate discussion they need to focus on.

Regarding limitations, it's much better to make small adjustments and see what works rather than updating everything while tanking framerates or latency. We have seen pushes and changes but a lot of this is going to inherently be an issue due to the underlying shoestring they've built the game on.

But seriously, fix dark knights.
