I think it's more that after a certain point, they're just not worth doing, even with how quick they are. Around level 25-30, I start wondering why I bother queuing for hests at all (even with only doing them via roulette).
I like the idea of achievements leading to unique rewards for in-demand roulette roles. The only way gil or seals or tomes is ever going to entice me to tank roulette is if it's so stupidly large that it (further) breaks the economy/progression. But if there are rewards I can only get by doing roulette as an in-demand role? Then yes, I will tank Sastasha some more.
