If you are doing the HW MSQ and you are playing a BLM who’s at level 82 where are you going to get ilvl 430 gear except off the market board for likely more money than you probably have
They also can't do 5/6/7/8 roulettes, expert or 90 roulettes even though they might be max or an appropriate level. Duty Roulettes are not solely for the purpose of levelling other jobs but to help fill in the roster for players completing these things for the first time by incentivizing other players to run them again. It is also a tool for gathering tomes when you are max level and have completed MSQ.
