The ideal outcome is they sack MSQ roulette, make those solo duties, and distribute the XP elsewhere. A little could go into the 50/60 roulette, which some people skip since they feel it's not rewarding enough. ARR FATEs and pre-Stormblood hunt marks could also use a little love. There's places you can go to get XP that are actually fun to play that are worth highlighting and are more flattering for what FFXIV should be.

Of course, they could take out MSQ roulette and not improve XP elsewhere, though that's still the better outcome so that new players can have a much better experience.
