I play a Subtlety Rogue, and the other day an Unholy Death Knight asked me to "quick cap" in 2's with him. The first team we came up against was a Resto Shaman / Arms Warrior team, and I was absolutely certain that the Death Knight would get tunneled down hard by the Warrior. To my shock, the Warrior stuck on me the entire match. I spent the next 5 minutes having to run around the pillars and barely being able to heal up because of Mortal Strike. Everytime I got a Kidney shot off on the Warrior, and bursted him down, I would immediately have to begin running for my life because my HP were so low (around 50% because recuperate wasn't healing enough because of MS). Each time I began to run, the Warrior would simply heal back up to 80% from the 40-50% I knocked him down to with my Kidney Shot and Shadow Dance.
This went on for about five minutes until I finally got a well-timed blind off, and Shadow Stepped to the Shaman and finished him. Before Warriors didn't seem that bad, but when Warriors can do more damage than me, keep me from healing, and out heal me, something has got to change.
