Can i suggest a khazix rework?

Passive: Consume and adapt Kha'zix gains 0.2AD per small minion or monster killed, and 0.5AD per large minion or monster killed (doubled for epic monsters). When no enemy champion has vision kha'zix he becomes invisible, making his single target basic attacks and abilities deal 20% bonus true damage. When an enemy champion has vision of khazix he becomes unstealthed immediately.

Q: Scythes of the voidreaver Evolved: Base AD increases by 35% and kha'zix next basic attack deals 80/100/120/140/160+0.5 total AD as physical damage. Khazix next basic attack deals 15/25/35/45/55+1.0AD as physical damage.

W: Wings of the hunt Evolved: Damage is reduced to 30/40/50/60/70+0.4bonusAD and kha'zix is not unstealthed for 2 seconds after use. (this is pretty much the same as his current leap)

E: Mark the prey Evolved: Kha'zix has vision of all enemies he attacks for 5 seconds. Kha'zix marks an enemy, causing all damage dealt to them by kha'zix to be increased by 8/10/12/14/16%+1% per 50AP

R: Voidreaver instinct Evolved: Kha'zix basic attacks ignore 20 armor At levels 6, 11, and 16 khazix gains an evolve point. For 3/4/5 seconds Kha'zix basic attacks put him in stealth for 0.75 seconds and gains 20/30/40 base movement speed for 1 second.
