Judging from that video I am confirmed in my assumption that the developers are striving more for a realistic, team based experience, rather than an arena for skill monsters.
This change would of course be a nerf to polearms, so most likely they will get a buff in some way, but even then their role will change. Not only the spear weapons, also the halberds will turn more to some kind of support weapon, which in theory adds to the rock-paper-scissors-system and makes the different classes even more individual. (Because atm there is only little difference between fighting with a DGS and a poleaxe, especially since polestagger got removed)
I voted yes, because those things are what I like. Make the battlefield more realistic, and the individual count less.
And yes, all you skill whores can downvote my post as you like, I don't mind.
