Buff empowered attacks

Pretty simple, if i'm hitting something that takes a set % of it's health, can i please not use up my empowered attack?

turret is a good example, as are plants. Basically anything that takes the same flat "damage" per hit, regardless of how powerful the thing hitting them is. I can't imagine this is a hard thing to fix, wards no longer eat empowered attacks.

Another work around, is to have the empowered hit count as 2 hit triggers for the thing.
