Teach me when to use Onslaught.

[Dinohazard]

At 100 pot for 20 gauge, it's slightly weaker than Fell Cleave and 2x stronger than Inner Beast...
Understand the move before calling it weak.

While I agree with everything you said in your previous posts, I failed to understand your math here: How is 50 pot/10 gauge (Onslaught) "slightly" worse than 100 pot/10 gauge (FC) and "twice stronger" than 70 pot/10 gauge (IB)? Onslaught is no doubt the worst "potency per gauge" ability for Warrior, thus damage-wise it is the least efficient one. Like everyone else said, Onslaught is only good when you need to dump extra gauge, or when you need its utility (gap closing, aggro pulling).
