Which raid bosses would you prefer over any current final boss in any wow raid?

I would replace gul'dan and make tichondrius fill his spot if I could Tichondrius is one of the legion's highly ranked generals or agents you say

Yogg-Saron and Imperator Mar'Gok are both spectacular final bosses, though I don't think Mar'Gok would really work as a final boss. I agree Tichondrius deserved way more fanfare than he got in Nighthold, that should've just been a random Dreadlord and we could have had Tichondrius show up on Argus as a major enemy.
