Would a "Swap Health Percentage" ultimate be allowable in League?
One of Mal'ganis' ultimates in HotS is a really nasty one called Dark Conversion.
Dark Conversion Channel on an enemy Hero for 0.75 seconds, then swap Health percentages with the target over 3 seconds.
You use this when you're low on health, and can quickly turn the tables on an opponent who thinks they can kill you. However, if you're interrupted, the effect fails and you'll die pretty quickly. Also, your opponent could still kill you before the swap really takes effect.
I imagine this would be extremely cheapass in League, but if put on the right Champion and adjusted appropriately (i.e. very long level 1 cooldown, can't bring your opponent below X% health, etc.), could it be allowable?
E, basically "you win, I press this and now I win. But if I win I win" and is the reason she got reworked
