The issues isn't the mode or the ranged damage or anything else than the amount.
As 1 melee guy, I can avoid 2 archers kinda decent when I try to get close to them. Sticking to walls, go around corners, try to get behind, not running a straight line and stuff like that. When there are blobs of 3 and more archers, it is just not possible...
Really good archers like Robin, Woodland, Nikodin... they are already hard to get when they are alone. Mediocre archers in blobs make that up with fire rate and their amount.
I don't pretend to have any idea how to solve this tbh. I firmly believe that the amount of them the is the real problem that needs solving tho.
