Teach me when to use Onslaught.

Honestly, IMHO it should be a resource generator, not a spender. At 100 pot, it's too weak to justify using it.

That's the point. The fact that it has low potency and costs BG means you can actually use it when you need it and don't have to use it on cooldown for the DPS gain, outside of your IR window. It's not a significant loss or gain to use it at any point in the fight.

It's one of the best-designed gap closers in the game, if not the best.
