This isn't a complain post, more just an FYI for aspiring DK tanks out there. I was replaced tonight in my guild by a pally tank with gear not as good as mine. Our guild leader ran a 'damage taken' test between me and a pally for the night betweeen Ony25 and ToC25. To make a long story short, he took 38% less damage than I didfor the night. Needless to say I'm on the dps list now instead of tanking. I wasn't MT, another pally in our guild is MT, but I've been 2nd tank or OT for a few weeks now.
Anways, I love tanking, I feel kinda bad but there isn't really anything I can do. I'm thinking of jumping on the band wagon and lvl up a pally. That way in the future if DK's ever edge out in front again, I won't have to worry about being sat out fo rtoo long.
