haha cool to be/feel like a ret vet...
i would skip the holy tree completly. you never need to heal in combat.
(ok, you do die sometimes.. but it's rare.. and usually when bubble and instant max hp and some mana, are on cd and you are vs elites.)
you dont want seal of command... (blood is cooler and better)
when mana is running out... seal of wis..
-"- health -"- seal of light..
bubble if hurt.. and use the instant "full healt and some mana" instead of drink or eat.. only 20 min cd now..
aoe all the time.. even if its only one mob.. your seals and judgments will make your mana and health to not go out so fast..
use blood if you want higher dps.. but its almost fster lvling with light and wis and the opposit judgement.. ex seal of wis, judge of light (or whats it called.. the yellow one).
spam the judgments..
thats how iw done this far..
AND the most important thing.. don't fall in love in beeing the best damage making (maby not dps, but damage done) class in the game, with minimum downtime. that boosts your fellow party members really good with aura and buffs, and also heals them whit your damage done.
we want healer! =)
gear nothing with int, spellpower or such if theres ap, streght and crit to chose instead..
a mana pool of 4000 has been enough for me this far.
i was specced something like this in the beginning i think.
http://www.wowhead.com/?talent=sZ0xZVfbx0uucrsguAovindication should be grabbed later on aswell.. i think... its nice with a 20% less int, str and so on on your foes.. iw never done one single fight where it not procs.. (if procs means that something kicks in)
