I feel that the sync should be reworked but not to get higher level skills, but, to match the difficulty when the dungeon/raid came out. For example, if you are synced level 50 and do the 24 raids, the 2 firsts of the series are way too easy because your ilvl is way too high for those dungeon. Level 50 means synced to ilvl 130 gear, while te maximum gear was 90 for the Labyrinth of the Ancients and 110 for Syrcus tower. Same thing happens when you do the story quest roulette, they fixed the cutscene problem for the new players, but there is no challenge for this big story dungeon, since the ilvl is way too high. The same thing happens for the dungeon/raids lvl 60, and already happens for the dungeons/raids lvl 70. The royal city of Rabanastre or the Ridorana Lighthouse are not challenging anymore since everyone is close to ilvl 400 now.
