Death Knights are waiting, and hoping, for some affirmative feedback and changes from Blizzard. This is a little emotional. I wrote a short post about this phenomena in the forums, on player participation in game design, and that our relationship with Blizzard requires they communicate with us. I drew some parallels to a Tale in the Desert (which Tobold is blogging on), Eve Online (whose council required CCP disclose more information on their efforts to reduce lag), and a game I used to play Achaea.
Consider has written a good Q&A on DK mostly from DPS perspective, but with a few good mentions of the tank issues.
Naha’s consolidated thread is still the best place for us. It’s well-organised, and I’ve made sure it covers all the key tanking concerns.
