1-It is boring to leveling, very repetitive quests, no challenging, takes long time to kill a monster, low drop rate, monster that run everytime you are almost killing it.
2-Useless skills at low ranks, that don’t help in the endgame. Gung ho and concentrate are examples.
3-The pets are so ugly. And the only ones that are not ugly, are not so cool, they are just simple animals with nothing special. I would like to see pets like, dragons, dinosaurs, wolves, tigers, and also cute pets too, like a panda, sheep, etc.
PS: I can’t forget of the bad optimization, that is the biggest problem of all.
