The problem isn't really incentivizing roulettes more than they already do; tanks get free mounts, healers and tanks get the adventurer-in-need bonus when applicable, they have a higher chance of more comms, etc. The problem is just A) too many people queue as damage dealers who don't want to tank or heal, and B) when applying to anything but Expert roulette, you risk losing all of the abilities you've been obtaining since you started your class, which just feels bad. These skills aren't even enhancements, they're integral to the job and make the playing feel so incomplete. For example, Gunbreakers get their Gnashing Fang combo at 60 and Continuation at 70. If I jump into roulette and get, say, The Vault, I'm stuck with a job that, under normal circumstances, feels fast-paced and dynamic, but now feels like a slog because I'm lacking the core burst combo that I'm suppose to have to make the job feel even somewhat fun. Even if I get into a SB leveling dungeon, I'm missing Continuation, a core mechanic of the class that gives it its fast pace.

Right now I have 5-6 jobs that I intend to get to 80, but I refuse to go into leveling or alliance roulette with any of them just because I lose my skills by virtue of being level sync'd down. God forbid I get Sastasha or Copperbell for the thousandth time and am stuck to using 2-3 buttons the entire dungeon.
