Why in the world Poison/bleed does not give onslaught?!!

Just why? oh god why GGG????

I have to HIT them to trigger my poison and so the poison killed the monsters and so they died from my hit, how is onslaught so freaking over powered that it requires hit damage rather than any damage at all to get it?

Onslaught is already hard to obtain and rare as it is so what kind of illogical nonsensical balance decision is that????

I would get onslaught on a regular hitting build which would make me attack faster and so kill faster so why the hell poison/bleed cannot do that? there's literally no difference! both require hits and will attack faster and so kill faster so WHAT THE ****?!!!!!

Make onslaught trigger on kills like in POE1, there's absolutely 0 reason for onslaught to have this condition.
