The addons did not in fact come out because the game was too overwhelming. I personally still use very few addons, but the idea of this is ridiculous.
Thinking players won’t use all the tools available to them to trivialize content even when they “don’t have to” is even more ridiculous. If the content gets simplified so damage is easier to avoid AND we still have defensives, it could get to the point where people start just not taking healers to high end content, or at least taking far less or forcing healers to optimize only caring about raw damage with healing as an afterthought. We’ve seen this happen before…
