Devourer Fix (Serious)

Why doesn't devourer work like Mejai's? Like whenever you die, you lose 5 stacks? It would be a lot more reliable than Mejai's, since jungle camps are a lot easier to come by than kllls, but it would give opponents some way to fight back, letting people feel like they accomplished something by killing Shyvana and adding more strategy for counterjungling. You'd have to add back the on-hit damage, and maybe some stat tweaks, but the stats and on-hit damage were never the problem here.
