Thank you! First of all, about the cost of his abilities, they are high because I want him to risk a close quarter engagement. With his passive, he recovers energy based on damage received, so in lane, if he plays too safe, he will probably run out of energy and won't be able to spam. I've already thougth about removing the cost on his ult since the CD is already high enough and that's probably what's gonna happen. But since he becomes immune to MELEE damage and abilities (So targeted ranged basic attacks or abilities will still hit him) I think .5 seconds is fine but I'll keep it in mind and see how I could tweak it correctly.

I also wanted him to need some good timing, but maybe I could adjust his own liftoff time on his ult to 1 second and keep enemies knocked up for just .5, we'll see. So thanks for your constructive comment and keep em coming if you have anymore ideas!
