I play all the 24 man roulette levels. Most of them I did in there prime too. Now with a roulette its not balanced at all. If I end up in The Orbonne Monastery its not the same level of challenge as the the first 2 Crystal Tower levels/dungeons. Plus some people don't want a challenge so they don't unlock the later ones. Not a crime but I feel it stops some dungeons from popping up more. Same reason I keep getting snowcloak as a 50/60/70 roulette. I do believe that labyrinth of the ancients need an item level sync of 80. Then bring Syrcus Tower to item level 100 or 110. Even The Royal City could use a little help too. I feel the reward is not balanced. Some people even back out if they don't get The Crystal Tower.
