Hey BIGPLAy, it sound like a whole LOT of fun, lol.
My comparison after the m4 was introduced was the T-3475...., its gun is is very underpowerd, and it is almost useless accept that most field ack bounces off almost every part of it but the tracks.
I didnt believe it was fair (and I still dont) that the sherman be introduced in its uber configuration, when the T34 was not..
I still believe the thing isnt perked enough, and see the panther being introduced as yet another awsome german ride that would be highly perked, and yet be meat on the table to the likes of the sherman...
I say bring it up to date with more gv's, but adjust the perk cost accordingly....
Im reminded that the reason the f4uc is perked is to keep people from flying only that version of the plane, perhaps the Shermans short barreld little brother would have the same effect on gv'ing if it was introduced...?
