I believe it's not the issue of high level, but impatience and attitude. High level players should aim for myth tomes (i90), which come from high level roulette, which cannot be really speeded-up. Low and main story roulette gives only gil and phyl tomes - both are quite useless, why impatient people que there i cannot understand - they are pretty much wasting time just by being there, no reason to be impatient. Well not fully useless - main story roulette = 1k gil + 9.5k gil worth materials (phyl tomes), and gil can probably be used to buy something too (but i haven't yet found what).
During my first main story runs i watched every cut scene - people didn't wait for me and went ahead, but i did those fights in the later roulette runs, and i do not regret watching them during the run - they were just great. The only frustrating thing was the team chat - i was doing the main game battle and discovering a large part of story, while some impatient dps were telling they need those tomes sooner.
So far my worst main story run was with a guy and his friend, who kept chatting between themselves on a totally unrelated to the game topics in the team chat during the whole run. It was even worse than those filler text quests and completely broke the immersion and role playing part.
