@Donjo - If you are referring to the lack of passives that increase the effectiveness of a cross class skill, then sure they could be considered inferior. But lets not be completely ignorant, flash as a cross class skill can work better on warrior than pld as a cross class skill. Not to say you'd be better off using it vs overpower, but then it doesn't use your tp resources.

Besides the -acc you get from the actual trait of flash, the main point of using it is aoe threat. Yet magically you can pop berserk on warrior, and now your flash is superior to pld. I realize nobody in their right mind as a warrior would waste berserk just to spam flash, but the point is it still gens more threat than a plds flash (with the same ilvl).

This is why I've argued that flash should have never been able to be cross classed to begin with; a remanent of 1.0. Originally I think the passive trait to it was turning it from single target to an AOE.
