You can't have good suppression, good setup/pack up time and 6 men durability. There's a reason that got nerfed in the past. OKW wouldn't stand a chance in the first five minutes on most team game maps.
Well it's not like there was literally any alternative to maxim spam at the time. Cons were and are trash who, *ahem* don't stand a chance Past 5 minutes against okw on all maps.
Maybe having something attractive to support the maxim instead of literally just more maxims would help elevate the spam of maxims. With t2 only having maxims and being an alternative to having infantry (because cons are literally worse volks who are only allowed to start scaling after tanks hit the field, not once they tech up for the 1st time) its literally maxims or bust. Bad faction design lead to a spammed MG lead to a nerfed MG that cant do its job unless spammed. It's a self fulfilling prophecy. As long as the maxim (and cons) are absolutely garbage, which they are, the only time you will EVER see maxims is in a spam. Because there is quite LITERALLY no other viable option. Penals or bust.
