This game has been around for 5 years and the developers never got to balance the stats and skills of each class though many players complained about it. There are stuffs that doesn't make sense in game. Like, you can't go to arena when you're in chaos rift and that means players has to watch their character grind for hours with auto battle. Also when players in hadum mode goes to arena they end up being in elion map AGAIN after going off the arena. Enough with new contents, fix them. :)
