What if only champions counter towards Kha'Zix isolation?

Imagine it, can't just place a tower and prevent 90% of your damage. Can't just ult, or can't just throw down their traps. What if someone couldn't simply stand next to a minion to negate all of your damage.

Would he really be broken? Maybe, but not likely, considering later on it's almost impossible to isolate people unless they are way out of position. Please Riot, at least consider trying this on PBE, or at least acknowledge that 's current isolation dilemma is a big problem. He already has struggles with early clears, it doesn't help that towers negate isolation and so do every single pet.

Think about it logically. You are alone and scared of a fearsome predator. You don't think "Don't worry this mushroom will keep me safe," sure, arguably towers could make you feel safe, so I'll allow that, but minions sure as hell wouldn't make anybody feel safe, other than supers.
