The game is ... really fucking fun. Not sure how else to put it.
The localization needs a bit of work and the tooltips can be confusing at best... but that's what betas are for.
The combat is a LOT of fun, even (mercifully) healing and tanking. It's all involved and very dynamic and fun.
My one and only gripe is the outfits for female cloth wearers. You're supposed to wear robes, not cocktail dresses or evening gowns.
I was really fucking sad when Arachnea crashed and didn't come back up until 2 hours before the beta weekend ended.
I think if they can clean up the tooltips and localization and provide an endgame as fun as the leveling experience they could have a real MMO that may not have to go f2p and could have a lifespan measured in years instead of weeks/months.
