its funny how fairly "new" players says , how easy those ones are to counter while "old" experienced players cant handle it .
if ur referring to groundfire, all he's doing is changing it so so the muni ht gets incoming fire nerfs just like engineers do. If something is planting/building something, it'll get an incoming fire nerf, it's not because it's hard to counter but because its unfair to be able to run up and while under fire just plant something, you can't do it with engineers, it shouldnt' be done with m8's, muni hts and pz grens
