Why You Shouldn't Use Fracture

[Kitru]

So basically there is one situation I can see if ever being used in then.

That's pretty much it (except that you don't have to have Berserk up to have it provide the relevant benefit; the comparative advantage/disadvantage remains regardless of whether you use it with Berserk active or not because the other attack would have benefited from Berserk the same amount, proportionately). Even then, in that circumstance, you're not even going to see much of an improvement out of using Fracture thanks dilution. You can safely remove it from your bar without worrying about losing out on anything really.

Not sure why you would give such advice. If you want to maximise your potential you should be maintaining Fracture in all single target encounters that you don't hit 0 TP in.
