% HP Runes (Seals)

So everyone is hating on these new percentage hp runes. When i think in situational circumstances they could be good.

So as the forum says in the link. Cho Gath would be an obvious abuser of this with his passive stacks.

But i am a support main who prefers tanks. I have noticed in games i get behind on levels as im warding and always sharing lane xp with someone, so the HP/Level, does not scale as quickly for me as a top laner for instance. But with the support items, i dont find it hard stay keep up in items, and also a lot of the best support items have HP in them anyway.

So i see the % HP runes to be good for supports to use, especially on Braum and talm kench, but also on champions like leona alistar and nautilus i think it will be beneficial as well.

Any ideas on the subject. Let me know
