Why is this an issue to anyone? How it was prior to ShB was that melees would run out of TP consistently on aoe pulls, where as this was a more non issue for casters broadly. Of course, if battle went on long enough, even casters would run out. But that was more an exception than the rule. This made the idea of "stopping AoE Spam" moot because the only ones who got stopped by that were melee classes. The changes made should even that out a bit if not slightly inverse it. If the pack isnt dead with this much aoe going out, then there's something wrong with the party.
