Because there really, truly, honestly are not enough quests, Vodomir? Is Lancer your first battle class? Is it level 46?

If so, you're going to find out why this is a debacle REAL SOON. Real soon. Story quest stops at 47, doesn't pick back up until 49. Vesper Bay/Sands hideout quests give a little bump, but not enough to bring you up even a full level. You WILL be grinding. Whether its dungeon runs or fates, you will be grinding, because you will not have a dang blasted other thing to do.

Enjoy, I guess?
