One day, I was running a few low-level guild members through Zul'Farrak. We finished the dungeon, and I took the opportunity to sit in his throne, informing my group that I had claimed the dungeon for my own and I was now the final boss.
We all had a good laugh, but that got me wondering. What kind of raid boss would players make? For me, my main was a ret paladin at the time. I sometimes pinch heal, too, so I think I would have to have some annoying healing ability, like the Twin Val'kyr when they use Twin's Pact. I love my bubble, so I would want to have that; maybe pop the bubble and cast a big heal. The raid would have to dispel/break my bubble and interrupt. Maybe some giant, AoE holy attack that opens up holy fissures in the ground. They'd do damage but make healers more powerful, to keep up with any enrage-like effects.
If you had to convert yourself into a dungeon or raid boss, what unique mechanics or abilities would you have? How would they reflect your abilities, unique playstyle and personality? What quotes would your character have? Would you have a cool story behind why you're there? Who are you as a raid boss?
