I agree with Barton that maxim is fine performance wise. The only thing I would like to be changed is the reiforcement cost. Now that we all agree maxim stats are not OP any more, not giving it the standard reinforcement discount all the other weapon teams have is just producing another inconsistency. And patches should aim on reducing the number of them. This is not an infantry squad any more.
Actually the reinforcement cost of hmgs are not really consistent since the value of the team weapon include an arbitrary value for the gun itself.
That is part of the reason why DSHK is cheaper to reinforce then maxim and HMG42 is cheaper to reinforce than HMG34.
