the only things that needs to be done now is to change the abomination that is called a maxim. increase its arc but give it a hefty packup time so people can actually flank this will eliminate the maxim spam bullshit
A hefty pack up time is a terrible idea for the maxim. It's gunner is easily killed by long range german units (ever more so with OKW) and you will just end up with a dead maxim even when retreating at 6 men with full health. Not to mention trying to retreat after getting hit by a long range rifle nade. Other HMGs don't have this issue thanks to them being shoulder-carried.
A better solution would be a wider arc + increased set up time. This makes the unit less A-moveable without increasing the occurrence of the gunner killed loop.
