Yeah, i was gonna say what Hasrat said. Open your dungeon list in the duty finder and it will show you the dungeons(and raids and trials) you have unlocked. The "Leveling" roulette has the Ifrit, Titan, and Garuda 4 man fights along with all the non-cap dungeons. The "Trials" is just all the 8 man(non-extreme) trials you have unlocked. The MSQ roulette is Castrum and Prae. The x0 dungeon roulette is the cap dungeons from all the older expansions(so lvl 50 ARR dungeons, lvl 60 HW dungeons, etc). The "Alliance" roulette is all the 24 man raids youve unlocked(CT series for ARR, Shadows of Mhach for HW, etc). Frontline is a roulette that rotates through the PvP modes daily. Guildhests have their own roulette. And you probly arent far enough along to have unlocked the Normal, 80, Mentor, or Expert roulettes.
