I loathe them especially now that most gap closer etc have 2 or 3 stacks so you feel you are going to lose damage if you do not start moving the cooldown...

Using an utility movement tool point blank just for damage feels weird, it is probably why i feel much better with Monk's new Thunderclap.

RDM is a weird case for me because unless i really need to, i always stick to Engagement over Displacement now that both have same damage and because the former is NOT a movement tool, i feel way better but at same time those 2 buttons shares the same recast timer so a bit planning or see the situation of the battle.
