Missed skills

If i dont do all the side quests, can i buy the skills i didnt get. What im trying to ask is, can i buy skills that i didnt quest to get. Im hoping i dont have to go back and do all the minor baby quests.

If you decided not to do all the "minor baby quests" then there should be areas throughout Tyria that have those skills available. They might not be in the areas though that you hit while running the storyline... you may have to go out and explore the map to come across towns/outposts that have Skill Trainers inside that offer the skills that you're looking for.

Happy hunting...
