Leo is talking about WWIIOL there :)
You either penetrate or it bounces off in WWIIOL. I like that. But BF1942 works when I just want to blow stuff up.
Grenades will not be useless against tanks in the next patch, just nerfed a bit.
I also think that bazooka's should deal out more damage to tanks for ballance.
AT guns would be nice as permanent emplacements. Especialy at the permanent, uncapturable facilities as they would make sense there.
