Nasus Slight Rework/Buff Proposal

Currently Nasus' ability to scale well to late game is by last hitting with Q. There are some situations where waiting to last hit with Q on many minions are not ideal or outright impossible, such as ARAM, Twisted Treeline, Dominion, playing Jungle Nasus, need to push a lane real quickly. Basically, Nasus gets gimped heavily in these situations and may not have the necessary impact to carry even when farmed (as in having a lot of gold, either via HA or CS' passive gold generation or by kills/assists)

My proposed changes: Soul Eater (slightly changed) Nasus siphons out souls from his victims (enemies killed) and store them as Soul Eater stacks. Nasus also gains additional lifesteal (lifesteal amount unchanged). Minions and small monster kills grant 1 Soul Eater stack while champions and large minion and monster kills grant 3 Soul Eater stacks. 2 Soul Eater stacks per assist.

Siphoning Strike (slightly changed) Passive: Killing an enemy unit with Siphoning Strike grants 3 Soul Eater stacks instead of 1, doubled to 6 Soul Eater stacks per champion and large monster and minion kills. Active: Nasus' next attack deals bonus physical damage (+1 per Soul Eater stack).

This means that like Sion, Nasus gets to at least gain some power the more he farms. More emphasis is still placed on last hitting with Q but not as important as before where killing enemies with Spirit Fire, auto attacks or any other sources completely invalidate Siphoning Strike in the long run. Veigar's Q is fine as it is because AP can be highly increased by masteries and Rabadon's while affecting his W and R's damage as well.
