i'm guessing tyrannis isn't getting enough kills in the 76mm sherman..
i dont GV anymore. i see no point to it. i used to love gv'ing. had over 300perks from it.
but then it just suddenly changed. ppl stoped trying to take gv bases and went to just camping the space inbetween sniping eachother until they get bored&log off.
or if your a small platoon of tanks assaulting a gv field, then the defenders will just spawncamp you till you get tired of being spawnkilled.
i droped from over 300perks to 164 from just being spawn killed alone. so i stoped gv'ing.
the 105mm sherman tho is one of my favorite. and i would pick up gv'ing again if it was added.
