I GV a lot and have been on the wrong end of a bomb or two. Making them miss is part of the fun though harder with competant players. I will bomb GVs advancing on a base as defense of said base and I will target the perk tanks as they will be harder for my sides GVs to kill. So up a panzer when your Buds have perk rides around you.
HTC hears your pain and changes are a coming.
