I just finished a CW battle where we lost 2-1, with the other side using 3 M60's. I can't help but wonder if the match would have had a different outcome if all our players had access to 330 HEAT pen. Maybe I'd be going through the front a charging IS7 with ease too.
Everyone who has an M60 runs it because of the pen. That's an unfair playing field putting an un-nerfed gift tank that nobody paid for in the hands of a few and not letting everyone have access to it. Either balance it or make it available to everyone. The thing is literally the new obj 140. WG didn't change the big picture of medium tank balance: a standout tank still exists (Obj.140 --> M60), but now only a select group of players have access to it.
The ending picture is more imbalanced than it was before.
