Man I was excited for this. Until I actually got in the game... i pressed my G key for hours basically while being told by my friends "wait until you get to 50, thats when the end game starts". After 40 hours of side quests (which were god awful btw) and main story (also awful and not memorable), I hit 50.
Wow. I wasted my time. 'End game was there and I realized that it was nonstop button mashing without reason against wave after wave of enemy, just to realize im grinding for materials to use to hone my gear and rinse and repeat.
I saw my friend hone an item at 90% 3x and fail them all. Its a total cash grab that steers you into paying because normal playing doesn't cut it.
The game looks great and at first, feels so satisfying. But it quickly becomes an unreasonable time dump that has you always chasing an unobtainable goal. They miss the mark in so many areas, but its not a 1 star. Worth it to try, being free... but it is not good in my personal opinion. The effort put in does not translate to any feeling of reward.
