Why didn't anyone tell me?

(Couldn't find a humor tag, and yes I know it's what I'm supposed to do) in HZD I pretty much ignored all the side quests, but in HFW I've been doing every one I come across of its closer than my main quest, I think I've gotten to level 16 by the time I've gotten to sylens little hideout with HADES. In ZD I was wondering why skill points were hardish to get. Guess I never looked at quest rewards lol.
