Player experience is something cant be balanced because first and last factor is players count of continent how many play together and how good they are. You think prowler is weakest tank but it isnt. This and every other items in game are +- balanced (maybe harasser is too fast and too armored). So, try it 1v1 with similar experienced player and exploit specific faction MBT functions. How players feel in real battle in specific situation is only only feeling making something "weak". And again, please stop making something OP or weak with no real numbers. In few months there are OP NC MAX, OP Vangaurd, OP VS laser shots,... your own experience proof nothing.
