Should Level Sync better not remove skills?

[VerdeLuck]

Yeah better take care of that newbie who probably is playing with a free trial or maybe he/she is going to do TamTara for first time ever and never touch it again(or until the sprout unlocks roulettes at levell 50) instead of catering to veterans who stays subbed and keep playing the game every month.

Don't do roulettes then, no one is making you do them and they are entirely optional. They exist entirely to serve newbies by filling out their duties and letting them progress in the story. They aren't for you, you're adequately compensated with xp, gil, tomes, and materia for your time spend helping them, but that's it. If that's not enough of a reward for you then just don't run them.
