Hiya!
Pre-grats if you haven't already reached 80!
If you pair up Stoicism and your Single target wards and wait till they fall off to recast them the heal at the end will add up on the parser..
As far as gear goes it really depends on your play style.. Over loaded heal items will come in handy and proc alot which add to your Heal parse.
My only tip is to carry around your Mana stone, power totems and acouple power potions as "Just incase" items :)
