Sena Hikari - Adamantoise Bunny Samurai that just hit 80 the other day. I'm almost done with MSQ stuff and am looking forwards to some end game grinding.
You can 100% go from level 1 to 80 doing just the MSQ as that is what I did. You end up doing your randoms for tomes anyway as it's a good way to gear up until 80.
