If you refer to retarded commanders that break with basic gamplay mechanics then the answer is NO! OH GOD NO!
If you refer to balance changes such as the veterancy overhaul or the +240mp start, then my answer is ok why not.

Not sure how I could answer this question without breaking the NDA but I agree with this 100%:
Don't worry (I'm in beta).
There are far bigger issues.
Thing is that it's pointless to argue about the current state of the MG42 right now. We need more people in the beta, preferably none biased to factions (looking at Nullist) and certainly not Relic fanbois. There's a lot of things to be solved and the next patch is closing in.
