Can Irelia's ult be updated to heal based of # of targets hit rather than damage dealt?

Irelia looks like she's getting a small buff to her Q in the next patch. That's nice and all, but there's one thing about her kit that's always infuriated me: the healing on Transcendent Blades. Use it on minions, the healing is almost broken. Use it in a team fight, you don't even know its there.

Why is it like this? Because it heals based off the damage you deal, which is drastically reduced if the enemy has even one armor item (as Irelia doesn't go for penetration). It's the same sort of problem Renekton used to have on his Q.

To that end, it'd be nice if Transcendent Blades could instead heal based on targets hit rather than damage dealt. This kind of change could benefit Irelia by making her ultimate's healing have some consistency, rather than being super wonky due to enemy armor.

Obviously numbers would be adjusted, so this wouldn't necessarily be a straight-up buff. It could even result in a slight nerf in terms of her using it against minions.
