I think it's a cool little curio of where you've been, the raid ones, but that's about it. Like having a mini fel reaver and curator's kind of cool... But it'd be a lot better if you could click it and it would use that boss's noises/quotes instead of just sitting there. A few do but not that many. Fel Reaver doesn't make the WAHGGGGG noise and Curator doesn't say anything.
I get that it would be annoying if it was automatic, but what I'm saying is Warcraft 3 style where you just click it and it'll say something. I'd much rather have that than slow as hell Pokemon battles.
Edit: ANd on the 'personalizing' note I was talking about before. The Temple of the White Tiger quest is the PERFECT chance for them to have done something unique for your race, but no, they just make you fight Wrynn/Garrosh. Would a Blood Elf, Troll, Tauren, or Goblin really hate Wrynn that much? Wouldn't a Troll have Garrosh or Zul'Jin? The Blood Elves have Arthas or Kael? The humans have Arthas or Garrosh? Could have added some serious spice there, and it's not like the mob does any Wrynn/Garrosh specific abilities. As long as it was humanoid, they could have done it and just removed the 'that's my father' line. I don't know, I just wish it was something they pushed more to help your character feel unique.
