Should Level Sync better not remove skills?

[Sesera]

What would stop speedrun minded players from kicking a tank for not having an invuln or a DPS for not having AOE because they're too low level to have those skills?
People already do whatever they can to clear roulettes as fast as possible so that would definitely add another layer of friction between sprouts and players levelling alt jobs, and people on their main jobs.

A trip to the jail and a ban.

also Dragoon/Lancer get first aoe at 40 and I never heard about lancer/dragoon being kicked before Stone Vigil.
