Champion Concept Based On Rock Lee (feedback plz)

Rock Jaw Champ Concept

Passive: Quick Fists or Fast Hands (whatever sounds best) instead of having his basic attacks do one strike that does 100% AD, he, at level one, does two quick strikes that do 50% AD each. This scales up by 0.7% per quick strike per level.

Q: Hydra Jabs/Three Finger Strikes (whatever sounds best) His next basic attack(s) does bonus physical damage and silences the enemy for like 0.5-0.75 sec

W: Rock Hurricane He spins around, kicking and knocking up anyone within the radius and does some physical damage

E: Speed/Drop the Weights/Detach the Weights (whatever sounds best) He dashes behind a single target dealing physical damage to the target

R: Hidden Lotus/Will of Fire (whatever sounds best) When activated, he gains what is pretty much 4 buffed charges of his E. The difference is that when he dashes behind them he knocks them back in a random direction. Each time he uses another charge, it will do 10-15-20% more damage, so basically it can be used for knocking the enemy back into your team (if they get kicked in the right direction) or it can be used for pure damage and cc. maybe 0.5-0.75 sec delay before you can use another charge.

let me know what you think and some improvements i could make. -The Shrill
