What if Kha'Zix got his execute back

As in, on evolved Q, even when not isolated. This way, he can actually do damage when not isolated, but isolated targets won't be affect too much seeing as how his Q would do half their hp regardless.

Kha'Zix is known for being an all in, jump in, dive kill, jump out kind of champ. He can't use his W mid air anymore because of past (WAY past) issues, and he can't dive because towers stop isolation. And he would need his E to escape anyways since tower would likely kill him unless someone else tanked, so he still couldn't one man dive towers until level 11, and even then he needs to get the kill or assist to get out, unlike some other champions .

Thoughts?
