Some MB are str builds, but no where near the amount of KUTT, I can count maybe 5 to 7 in MB that are full str.
Idgaf what builds people use, it's just that KUTT/MB's
average armor level is pretty high (Heraldic Mail up to Light Kuyak or Transitional), even if it is brought down by a few people in Lamellar or Fur Coats.
I swear I haven't seen Negga wear
anything other than his
Heavy Light Kuyak/Black Gloves combo for months, which if heirloomed is
51 body armor. THIS isn't terrible in itself, until you consider the fact that he's going to be team-balanced based on banner instead of any reasonable and equitable variable, which can lead to some really unbalanced teams, which frankly isn't fun for anybody. So if MB or KUTT are all wearing heavy (40+ body armor; yes, that is a high value, yes, that includes gloves) and are balanced on the same team they're at a serious advantage regardless of builds involved.
The easy answer, one that I've been lobbying for for month after month now in all modes, is changing away from a system of banner balance into something based on more concrete values like loadout cost, stat allocation, and performance.
