Vangu, liked your guide, though I build and playa bit differently as him, might write my own some day. I'd like to say though, for your masteries, Perserverance may not be worth it. Think about it for a second. A 4% boost to regeneration effectively means that you gain 1 extra regen per 5 seconds for every 25 you have. If you had say, 10 regen per 5, that would mean it would add 0.4 regen, which would mean you'd need to wait 2.5 seconds to gain one extra regened point of health or mana. It is ncie that it adds both, however, I'd reccomend simply going for Meditation and the mastery in the Defense tree that gives 0.3% of your max mana in health regen. Every 500 mana translates to 7.5 HP regen per 5, easily obtainable early.
