Took me a while to find more efficiency from Skill Tree:P

I quit using Blade Shield, Venom.
Instead I maxed Tiger Strike and Combo Mastery in Martial Art tab - both increase dmg per active charges.
*Making it a wind-up type of use - it doubles Mind Blast's damage
+adds a single target skill (Tiger Strike/melee), which Shadow tree lacks.

At maximum active charges make MBlast 6k into 15K dmg + multiplied by 250%crit modifier
so it's a major DPS+ / charges last 15sec, so have to re-wind after that time
bit clunky but doubling dps output worth imo.

To be continued...
