Honestly, i couldn't care less for numbers, it is to much math people put in such, eather enemy dies fast or slow, end of story for me, saem for healing, it does its job, not care how much i heal at the moment and not run out of mana due anything. People want ot much details on a game forgetting it is a game to have fun with mostly and not do a math project on things. Potency means onyl for me it is higher, AoE has potency as example and a little math i allow here seeing that AoE always more potency then single target when there are at least 3 enemies normally. But thats it for me, it gets its job done, i not see why people seem to possesed wtih numbers and details honestly, highest DPS ranks, or calculating the perfect starter combo.
