To me it seems 5.0 felt like a soft restructuring for the majority of the game.

We're talking no TP, Tank stance reworking, the healers being changed, aggro changes, pruning.

The way I see it is from this point onwards can only get more advanced since we're pretty much near the point where you have to be braindead to not understand this game at a casual level.

I'd be worried if the ceiling became even lower since I'm not sure how else you could do that past the game shoving your actual rotation in your face like a PVP combo.
