Just noticed the flail in the video, that's something to be excited about!!
Spears for 2hand, Flails for 1hand. I'd freak out.
If they do either/or, or even both, I'd like to see them "Go all out" though, and make them fit in the game. IE, add them properly to leveled lists in loot, and on appropriate enemies (I see lots of Forsworn using Spears, and Vigilants of Stendarr using Flails)
