The quests feels super unbalanced. I'm currently level 67. Some of my quests takes 5 minutes to complete and gives me 500k - 900k XP. Then there's quests to kill 100 - 300 mobs which can take over an hour to complete and they only give you ~500k XP
Then around level 50 there were easy and fast 10 kill quests that gave you the same amount of XP.
Everything just feels so unbalanced. Has the developers came out and talked about these balancing decisions somewhere? I'd love to hear their reasoning behind this.
