I think my death knight may be finished. It's not the class or spec. Unholy has been fun. I really like corpse explosion. It fills me with a joy that I've not felt since I first AoE tanked SH and watched the pop pop pop of seed of corruption.
The problem is Outland. I'm sick of it. I want to punch Hellfire Peninsula in the face. Or better, kick it, because I'm not very good at punching. If I could at least get to Nagrand or try some instances it might be okay. I'll probably push my way up through the levels eventually, but I don't anticipate a quick process. Once we have Wintergrasp back I'll get the heirloom shoulders. Those will help my warrior and DK, so the investment isn't too bad. Besides, what else would I spend the tokens on?
Recently I got an answer to my question: "What happens if two people are grouped up and in different phases?" It turns out they can't see each other. This made for an interesting challenge when trying to guide a friend to a quest mob in Icecrown. This also explains why Icecrown felt so empty, lots of the people were in other phases. I wonder how this affects mobs and skinning. For mining I've actually run into nodes being mined by someone else. At first I thought it was just lag, but repeated "already in use" and nodes with a single tap on them seem like pretty convincing evidence.
Championing hasn't turned out like I expected. I thought it would be a flexible way to gain rep with whoever I wanted. I was wrong. See, I didn't think it through fully. I never thought of all the times I did an instance and got no rep because I was already exalted. I didn't realize the speed of rep gain caused by concentrating the gains, instead of three instances going to three factions, or maybe none, instead three instances go to one faction. Rep overall might also be slightly buffed, since I seem to be getting 1.5-2k per heroic, which feels high. I will be surprised if championing doesn't turn out to be one of the biggest and best changes in WotLK, though obviously beaten by phasing.
Back to my DK and unholy, I finally see the point of Reaping: More unholy runes mean more corpse explosions. This maybe be the second greatest talent ever, second only to corpse explosion.
