Never had a problem with polestagger really. It's only a big issue if one gets behind you. Honestly polearms need something as they have really shitty animations that telegraph their attacks quite obviously. Aside from a good right swing, they don't have much going for them. Parrying a polearm is ridiculously easy compared to a 2-hander or 1-hander. Let them keep their stagger.
Parrying 2h is not harder than polearms, only quick 1handers have advantage.
Poll result is clear.
Only 18% of crpg population need to compensate their skill with broken mechanic.
2h are not superior over polearms at all, only advantage 2h have is stab length.
Polearms have versatility, damage, feels faster on same speed rating, shieldbreaker bonus, instant stab and broken animation (look like some frames missing).
Except of hoplites polearms dont need polestagger to be effective. Spears (2 direction specially) have ridiculous high pierce damage and are extremly effective in clusterfucks and group fighting.
