I started grizzleheim at level 46. By the time I was done with all of the main quests, I was only a level 47. Most quests at the beginning only give around 90 XP! The quest to defeat Jotun and his brothers, who are harder than malistaire, gives only 500 EXPERIENCE! I went through a ton of battles with enemies, and fought 3 very hard bosses, and only got 500 EXPERIENCE? That battle took over HALF AN HOUR! Because of the very low experience, I had to do a TON of side quests to get to Grandmaster. I think it should be fixed.
