I didn't like the change when it was first introduced, but after having spent time with the new glancing blow mechanic, looking objectively at the game it was the right thing to do.
While many of us old school twitchers were used to the playing a certain way, leveling the DPS playing field for newer/less skilled players was a good move. If you truly have skills, you will be top DPS anyway through just better/more experienced play.
To me moving while attacking is something completely different than shuffling in place while attacking. It has now become a trade off between moving to be defensive, and being stationary for max DPS. One can still use "skill" to semi-exploit your weapon range vs. a mob's, allowing for incredible damage avoidance, but it will come at a cost. Seems fair to me.
We still need to test the U9 changes, but on paper it appears what's coming will further widen the gap between stationary and twitch attacks.
