I actually don't do alliance roulette, or most other roulettes, as often as I'd like anymore. Sucks since I enjoy the bulk of the content in alliance, trials, and normal raid roulettes and would love to contribute to the solution in alliance rather than the problem, but it's just so easy to get my weekly tomes elsewhere while doing things I wanna do for other reasons, and I sadly have no other incentive to run those roulettes (other than just for fun, which takes a backseat to fun plus rewards). Elite hunt marks here and there for the tricerotops mount, frontline for the mining mech mount (which, admittedly, is more "rewards" than "fun" for me, as I've never enjoyed or been good at pvp in any game I've played), Kinko's for my weekly coin...I'll do at least one EX queue for the guaranteed WT sticker, but anything beyond that isn't guaranteed to be part of my weekly plan anymore if I get enough tomes elsewhere.
And yeah, I'd say 90% or more of the times when I still did alliance were something in CT, usually Lab or Syrcus. SOMETIMES I'd get a Mhach raid, usually Ark or Weeping City. I barely ever see an Ivalice raid unless I manually queue for it (which, as stated before, takes forever), and I've NEVER seen Kinko's in roulette (not sure it's actually in alliance roulette, but it'd surprise me if it wasn't).
