You're welcome on the feed back :)

My idea: Make the ult have a static cooldown. Mana ramp-up could be slightly more interesting (Mana-cost increase per flux). Also, now I see why you implement the slightly underwhelming Nether-blade Nerf. No need to nerf it more. And the thing I meant with the shield is that if he hits, say, Null Sphere right before going in he'd absorb some of the burst/damage :P

I still stick to my earlier stand-point of lowering the per-level increase of the shield and lowering the health-cost on his 4th ultimate. Maybe even make it ramp up a bit per flux? (2.5, 5, 7.5, 10% current hp?)
