The requirement is there so that it will come out around the same time it used to (1 CP)
I know why they did it but it didn't make sense to keep it, what's your excuse for the best and second best MGs in the game being T0? What, being able to produce the MG34 right off the bat is going to break balance as much as the USF Mortar is currently or something? If weapon teams in T0 are hard to balance then move all of them to T1 but that includes everybody, and yeah I'm really not talking about Soviets cause I don't really care about them.
Producing a single MG34 and then an sWs/sturmpioneer/volk/kubel/raketen is not going to break anything, if anything it will just help OKW secure a position earlier to setup, if the OKW player so much as to decides to go full spam on the MG34 like the Wehr can he's good as dead since he's clogging up his production, and yeah I know Wehr can't tech if they keep spamming MG42s but still they can get a good 2 or 3 out as well as have T1 down before needing to tech up so his production is not as hampered as OKW's one would be.
