If you had bothered to ever play USF you would know that before Rifles were buffed they would bleed USF a shit tonne which meant you often couldn't afford to buy armour because of the MP drain and I would have considered them the weakest faction in 2v2 and up (especially when you consider all the other thing sthat have been fixed / buffed since then). Even when M36 and M10 was buffed rifles still caused massive bleed. So to quote you "shows how stupidly biased you are". Bars were also less useful since they have been buffed relatively recently.
Bullsheep. The differences between usf and ostheer infantry hasn't changed much (especially not in 1vs1 and 2vs2 where vet 3 units are far less common) safe for vet 3. if you where bleeding mp then you are bleeding mp now.
The real problem back then was the usf and ostheer lategame the ostheer used the callin meta and dealing with 2 tigers with pak support was nearly impossible to counter. and guess what? rifleman being shot at by tigers will indeed bleed a lot of mp . and since the pak howie was really overpriced and bad back then the ostheer player could easily turtle.
For the okw it was the obers luch combo that caused havoc on them. with the captain route being utter shit the luchs could easily push the usf back into the base.
Bars by the way where buffed midway wfa ( i believe is sept 2014) so that makes your argument that bars got only recently buffed false and furthermore rifle flame throwers and lmg's got nerfed.
it was never the rifles that where the problem.
