In BF1942, the Japanese side are carrying StG 44 and MP-18 SMG. Their bunkers were armed with MG-42 and Todt coastal battery.
In 2002, you are beggars and you can't choose.
Back then with the never seen gameplay was new, so you could oversee this easily. And with the patches they tried to fix this, e.g. the type 96 MG.
But on the other hand, this is 2016. In particular the newer battlefield titles throw so much varierity and gadgets on you, that some limits, e.g. only certain factions carry certain weapons, could have even been beneficial.
Just think about RTS games, e.g. starcraft, where you find several heavily different factions. You can only master the game, if you master the specialities. Such a concept could easily fit into multiplayer shooters aswell. And we are back to a game like FH2 and its sometimes assymetric layouts.
