They are overused. Game focuses to much on dps. Even for tanks dps is more important than mitigation most of the time.

Personally I'd like to see mechanics in encounters that actually require the correct use of skills like leg sweeps, blunt arrows, shield swipes and even sleeps, heavies and binds.

At the moment all the skills associated with these abilities are spammed solely for the dps increase they provide. The way things are presently they well as well not exist at all.

Be nice to see things that had to be pacified or stunned or groups of mobs that had to be slept or heavier and kited.
