While i appreciate what youre saying, and not wanting all factions to be made too similar....
With all due respect after years of the game being out... relic simply fail at asymmetrical balance and always have. At this stage, id rather just played a balanced game than cling on to a broken one for nostalgia. The balance (or lack there of) is what has driven most players away from Coh2, and is effectivly going to kill it. Aslong as when theres only ever 10 players searching automatch you dont sit there wandering why .
Back on topic: 5th man in the squad is one option and im not entirely against it since squad spacing will not save grens from some squad wipes and the cheese than is allied AI capability.
But i think before making them a 5man squad, we should try giving them the better spacing and instead nerf the allied infantry down to the grens level a little with the 1 LMG and see how that works for a while.
I just feel that solutions like this are a band-aid at best, and don't actually work to fix the problems inherent with the game. It's because there is not enough effort put into the game to make real changes that can still have asymetrical balance, but relic only adds shitty attempts. USF mortar is an example; instead of adding a new mortar that functions uniquely to the faction (like what was in the beta...), they added in a normal mortar that is the same as all the other mortars in the game, but just straight up better stats. Weak band-aid attempt at solving the problem.
