well i remember at some point they'd added the rook, beserker and treasure hunter classes but aparently they've also added on a ninja and morpher class (the later letting the player transform into a mech/magical girl)
they've added the new region to explore for story mode, cegris, which also brought in some new characters (not there yet tho since i want to clear all of granvia first)
there's more pets so aside from just the pet limimin you can get a dragon or fox and some others (i've only got a limi and a dragon so my next goal is the fox)
they're also tacking on new event and monster quests so the new monster type stellar has some stuff i wanna see/learn more about. they've even got more options for upgrading gear (idk how they work yet but i'm figuring it out)
and on top of the battle colluseum and the tower of judgement they've added this crystal assault thing for leveling so the more damage you deal the more points you get which translates to items you can exchange
they also upgraded the stuff you can add to your room along with a fishing area so there's like a "town" map now (p sure they're adding some kind of market or trade function too judging by the coming soon preview they've got)
it's probably not a whole lot but it's enough to have got me interested again
