@ Centuriarch: I don't say that the self-inflicted damage is bad or too punishing - since not only is flat damage (thus, reducible by increasing the health pool) but aswell, as you said, any form of health sustain will mitigate the damage - I say that feels like the self-inflicted damage only exist to justify the short cooldown of the ultimate.

"Also, Darius has to stack his bleed first, he doesn't get that instantly." <- I know that, thank you for your consideration anyway, but thats the reason I said " with full ". Perhaps I should had said " against a target with  fully stacked" to not be missunderstanded.

And yes,  doesn't endure for thirty seconds, a passive damaging AoE that ease last hitting isn't good.
