No, it's easy to counter them in 1v1, as it should be for all support weapons. Try countering a pikeman when he's supporting a two hander or a polearmer.
Yep, and that is a HUGE problem since they're so god damned effective in groups, I see 3-4 guys with polearms and 2 handed swords and I'll recklessly rush and probably win depending on who they are, if I see 2 guys, one of them with a long spear or a pike, I cry to myself and commit suicide because I know I can't do jack diddly shit about it.
It's just how cost effective they are, they're 2 slots so every 2 handed heroes can get one, they're unexpensive, in support they're EXTREMELY good in part because of their reach and polestun, then if you get near them to eliminate this threat, LOL NOPE he blocks or do the circus fighter and you die a horrible death anyway.
Oh yes, and let's not even begin with the extremely fucked animations of this mod and game.
