A few pointers:
-Use Osiris Helm since 1 more crit and 1 more dodge is more useful than 1 hs and 2 ms IMO.
-Take a point off shatter and move it to Avian. Yes it does not unroot but it is still decent damage when you are out of moves to spam or when a bear lands beckon. Not to mention you can stun with it and do super repulse(Avain Repulse)
-Use Isis Helm, Wing, Armor, and a Shiv Talon for regen
-Your acrobats fine platinum band is level 10, level 20 version has 2 more damage.
