The DK that is the OT might make a better MT. I currently am the MT and am a druid tank but the DK seems to have better threat gen then me?
Is this normal or am I doing something wrong? I am following the rotations and such or are frost DK's just that good at generating threat.
Frost DKs are ridiculous at generating threat. You're probably not doing anything wrong.
I wouldn't be so quick to blame DK buffs. Maybe you're doing something wrong with your gearing or spec, or maybe the DK is gearing entirely around threat.
Or maybe he's getting Tricks/MD and you're not.
Or maybe he just needs to calm down and stop waggling his e-peen on Omen. You only need enough threat to outthreat your DPS, not your co-tank.
Hard to tell without armory and/or logs.
