Akee.... well I am almost at ascension... and for the last 18 levels I have been pondering whether being N/W was a good choice over N/Me or N/Mo.... well now is my chance to find out I guess(that and unlock skills w/o making a new character

). But im just puzzled over a few questions:
1) If I change professions, how do I get new skills(buy em, do old quests?)?
2) If I decide to go back to being a warrior(I assume you can by doing a quest), will I get my skills back?
3) How hard are the quests?
Appreciate it
