I have done about 80% of the side quests available to me as I made my way to level 50, I was on my first level 46 story quest as I dinged level 50. I had maybe 10 to 15 FATEs done total from levels 1 to 50 on my character. Only thing I did to gain some extra experience was run the manor instance about 10 times and rest of the instances about twice each for some gear along the way. Never did any Leve quests or any other extra means of experience gain on my main class.

So how is it that people are getting stuck at around 40 to 45 mark, while others are able to ding 50 with a plethora of quests left over?
