I started the game days before and have been playing Bladestorm for quite a period (almost Lv.70), and having some feedbacks/overview/suggestion for the skill.

Overview = Underrated

Good point:
Fun to play
Satisfying enough - Rolling around
Interesting Interaction with passive tree
Funny spinning animation

Bad point:
Kind of clunky in hitting and animations
Skill descriptions are not detailed enough
Sometime stuck in packs of monsters

Suggestion:
1. Since body-blocked is a thing in this game, and bladestorm is designed for slaughtering packs (I guess), perhaps giving bladestorm an unique feature that allows player to pass through monster while using it is a really good idea, not only improving the skill but surely the game play experience.
2. Based on my observation, it seems that the skill is only hitting around 2 times in each second. It makes the skill kind of clunky, it would be better if it can hit more frequently. (May be lower the damage for each hit and increase the hit rate in same proportion?)

Cheersssssssssss
