To begin with, you need to grind to complete several of the levels after 35(ish). The mobs don't give much xp. You will need to farm for a good chunk of time to get the next level. Second, quests are easy enough to do but they don't give nearly enough xp. even boosting them by 20% won't give you your level. At most the quests at later levels will give you 1/2 a level and you will have to grind the rest. (if you are below level, which is the entire game lol). Either add more quests or adjust the amount of xp you are given when you complete a quest. Third, we have to grind mobs to level and the xp from the mobs is TRASH! it appears that the mobs have a set amount of xp they give if you are under lvl, at level, and above lvl. It doesn't scale with your level at all. I'm currently a lvl 47 farming lvl 60's and they give 297 xp. A level 50 gives 250xp..... that's unbelievably stupid. Please fix some of this. Two of my friends already quit cuz they felt that they shouldn't have to start grinding at lvl 37. I know many more will follow them.
