Acutally I think this solves a lot of problems. Avoidance twinks have always provided a nice counter to the over-abundance of rogues..............instead of overpopulating the bracket with hunters it gives other options. Now that resilience is nerfed, avoidance twinks will suffer at the hands of casters.....which should see a rise in numbers.
The main three classes that roll avoidance twinks, Rogue, Warrior, Pally, are all now without their movement altering abilities. BoF, Hamstring, and Sprint all gone. It's going to be a lot more difficult to keep everyone front facing now.
It's a win, win, .............. win.
