The maxim is in a weird spot, its supression is kinda meh without vet but i dont think it needs a buff.
its rather mediocre performance early on gets compensated by a durable 6man crew, decent damage and a fast set up time. you cant really buff the maxim without taking away its upsides
any buffs for the maxim will result in the old maxim spam meta, which is a scary thought. i guess you could move some of the vet2-3 bonuses to vet1 or vet0 but thats about it but im not even sure thats needed.
The old maxim was op because it was very mobile and supressed a lot faster then now. Its mobility and supression where lowered substationaly in exchange for a larger arc and a price and build time increase.
The deathloop makes the durable 6 men crew quite redundant imo. Its not more survivable then a 4 men mg.
Since they cant fix the deathloop just make it 240mp again. This wont make the maxim spammable just as the 10mp for volks didnt stop okw spamming them. It will still be a worse mg just with a slightly lower price then its much better counterparts.
