I think you're referring to a general issue with lag compensation (and the bots, ofc). All weapons can appear to shoot through solid geometry under the right circumstances. Overdriver is I guess easier to spot given the projectiles are more prominent vs something like beserker

i must agree its probably just lag or glitch due to connection between you and their server.. i see weird things that should not happen all the time.. like a mech running around with revokers, obviously hitting nothing but in the end killing his target quite rapidly. its all messed up between what you see and what really happens..
