Just checked out Hahnsoo's PvE guide (great stuff btw!) and had a question. I bought every single skill that the Ascalon City trainer had to offer, whereas in the guide it mentions that no skills should be purchased here since they're all available through quests. Is it pretty much impossible for me to fully complete the game and unlock all of the Ranger skills b/c I wasted skill points with the Ascalon trainer?
