If there is one thing that I have felt on my Dk since the release of Cata. It is that we are always just behind the pack in terms of mobility. I personally can not think of another melee, and few range that suffer the same issues that we have. When compared to other melee specifically we really do premiere sub par.
Warrior: Heroic Leap, Charge (2x or 12sec cooldown accompanied with stun/snare) Intervene
Rogue: Sprint, Burst of speed/Shadow step, Preparation (Killing spree can even close a small gap)
Paladin: Burst of speed/Long arm of justice/Speed = holy power talent, Hand of freedom (2)
Monk: Double Roll (added with momentum or extra third roll) Flying serpent kick (All on short cool down)
Mage: Blink, Alter time
Lock: double port/burning rush
Priest: Shield sprint/Angelic feather
Druid: Travel form, cat form, pounce/charge, shape shift freely out of snares and such, Cat blink
Shaman: Ghost wolf form, Spirit Walkers grace, Enhance sprint.
Dks: Grip, Unholy Pres, Deaths Advance
Now I'm sure I have missed many of the other small speed boost. But looking straight at the DK all we have are 2 short increases UP/DA that together equal about 55% increase. Nothing compared to 70% Sprints. And a grip, Which most of the time the class can immediately roll/leap/sprint away.
On paper it seems like we do have options, and even more than some other classes, but in practice we do not.
PvP: Depending on comp, you will almost always go Asphyxiate. Unless you are rolling with a hard stun comp and it's not needed, then you will go chilblains or even possibly DA. Which DA is nice in theory considering you can't be slowed below 70% AND a nice 30% speed buff. So in theory you have a 40% speed buff for 10 sec. However, on any melee comp you will crumble if not in blood pres which takes away the unholy pres speed buff. We can argue all day about why dk's are so squishy that we have to sit in blood pres at any competitive form of pvp. The problem really comes down to, once we get past the few mobility utilities we have, we are more or less a giant slug with a axe attached to our head through pvp. Sure, are power is there, Frost and Unholy both have good damage. But it means nothing when you can't catch the target. For this very reason Unholy has become the spec to be. Range damage/pets/diseases. Sure we can be kited, but most of our damage is garg/ghoul.
I've lost count the amount of times I've been kited an entire fight and killed, and nothing I can do about it.
PvE: the issues is lessened due to raid platforms only being so large, and you can actually be permitted time to move into position before a mechanic happens. And I even go engineering just to have some mobility in raids.
So my question is what do you all think about the state of DK Mobility?
I would also remind everyone that I'm not looking for a big overblown argument. I'm merely presenting my thoughts and looking for constructive feedback.
