I've been a long time Warrior through the end of wrath and till the end of Cata, but decided that my first character to gear up was going to be my DK for MoP because frankly I was sick and tired of Warriors being at the very bottom of the barrel and wanted a change of scenery. I had always enjoyed Dks for their self-healing and strength. I'm very much a PvPer but I really did enjoy their tanking mechanics; blood boil always made it easy hold and pull agro, and DS didn't hurt either.
Anyways....I got my DK to 90 and was really enjoying the him and all that he has to bring to the table, but I am starting to have second thoughts. As I am doing 2v2 with my girlfriend (Hpally), we are seeing a large amount of Warriors now, in 70% of the comps. It's really making me miss the pure mobility that Warriors had and the fact that they can be halfway across the map with a leap, intervene, charge. Not to mention that fact that they got a very big damage buff this season (which I'm sure will get nerfed, as they are Warriors anyways :P).
I really have trouble with the rune system that Dk's have, as it can be very easy to abuse all your runes too quickly. Not to mention the fact that the only CC that Frost DK's have is a root from Chains of Ice via chillblains, which most classes have some ability to just plow right through it. Not to mention, if I'm constantly rooting, I'm losing all my frost runes therefore hindering my burst damage.
I really don't want to sound QQ at all, I think both classes are great fun to play, and I am enjoying my Dk as it is. But I just wanted someones second opinion on whether I should level a Warrior up, or if I should just shut up and play my DK.
