I'm going to be 100% honest... You can't call Alliance Roulette when 95% of the time it is a crystal tower raid. What I suggest is getting rid of the Alliance roulette and create a a daily rotation of the Alliance raids. I'm tired of people undercutting the ilvl to guarantee a CT raid. Grant it there is still people doing ARR story, but a solution to that is put Crystal tower also under the MSQ roulette or give it its own duty finder. Yes CT is fast, but its dreadfully boring and getting extremely repetitive.. OR reduce the 50 weekly tomes to 10 though I don't recommend reducing the weekly tomes.
