I played lots of hours, it was great at first but then i started get bored. Dungeons are cool but dungeon queue system sucks a little bit.
-When you enter a dungeon, noone wants to be tank and healer. Usually you don't die at the low level dungeons but it's annoying without a tank and healer.
-I don't know why but it feels like the game is too slow. Feels like game runs on low fps, you don't get the feedback fast when you press a button.
Also if you don't buy bag extensions with real money, it's really hard to fit all the items in your inventory and bank. I bought it after few days later, i get bored of the game and stopped playing.
I was playing 18 hours - a day this game, it wasn't waste of time i think. I enjoyed it very much. Daily/Weekly events are nice and fun way to get level up quickly
