Talent build that I would use, flex points are any concerning Mana cost, but the rest are pretty crucial. You could also pick up the +hit talents depending on your playstyle.
Gear loadout that I consider BiS but it does depend on how you value Int vs Spellpwer.
Thats how i see it aswell as soon as i see someone healing ally side thats target number 1 everytime, only class i would think about going hvy +healing is pally because they have lots of utility + mail + shield , tank asimo you should stam/int stack so a lot of the green pieces go of the eagle and all enchants should be stam, think of yourself as a tanky healer because if the other team has good players they will target you and +healing gear is nothing if you get wrecked everytime. more survivability more heals you can dish out!
