Kha'zix W evolution is still a noob trap as ever. Why not make it hurt isolated targets more?

Just like his Q, make his W inflict significant damage if it hits a target that is alone.

How much extra damage, I don't know. But it would define his gameplay a little more. And give him a source of damage other than Q-ing isolated targets. Now he can W isolated targets...yaay...

Will it finally be worth an evolution point now? Because don't delude yourself, his W is still garbage. That supposed "buff" does a whole lot of nothing for Kha'zix, and you'd only consider getting it just because his R no longer reduces damage taken.
