Kha zix support

Sure, why not, you'll get downvoted into oblivion for daring to suggest that anyone's personal preference is less important than trying to contribute the most to your team. That is the way this group of players thinks "Me. First. Everyone else, dead last." I'm being sincere, here. It really, truly is the prevalent view of this group of players that you can play literally any champion as support, and anyone who says otherwise is a worthless piece of shit who has nothing to offer whatsoever. So, while I could get into Kha'zix's relative strengths and weaknesses as a support, it really, really doesn't matter. It's depressing, it honestly bums me out that people care so fucking little about their contribution to the team, but....its reality.

I would say it isn't exactly viable since you will be facing a duo lane. As such your isolation passive won't be available as often

Well. One of your skills makes for a decent poke and slow. Your opponent likely won't expect you to be the support, and likely won't be prepared for it mentally. You have an escape, or a gap closer, depending on the situation. As it's a duo lane, you likely wouldn't be investing heavily into your Q, since your passive wouldn't be open too often.

I played Ez as an aggressive poke support, and won the game with 1/1/11. The other lane was stuck behind their turret, and their ADC was scared to even get cs, even behind their turret, while my ADC was able to free farm and dash up for a kill when they were all buttered up for him. Obviously, the game didn't last very long, or else that score woulda been better!

The evolved slow it's pretty disgusting but aside from that I don't know, his kit is all about dmg and you'll have none. Like what are you gonna do? Tank and bait people?

Id say you have the ability to catch them, but no kill potential. Your slow is kinda nice, but as a support you lose:

Your duskblade passive (duo lane, no isolation)

Damage (no gold)

Stability of your team (non-premade would report for trolling)

1 item slot (warding junk)

Prolly the lane (have to wait to 6 to evolve stuff)

Just dont
