This is the main reason I won't run Alliance Roulette. I'm sick of Syrcus Tower and Labyrinth.
Personally, I feel taking off gear to force these two is an exploit and I'd like to see it stopped because it has to be hurting the experience of newer players who want to experience all the raids.
However I wouldn't be against increasing the rewards, since that seems to be the main argument against change, that the rewards are not in scale with the difficulty of something like Orbonne.
