Well i must say i was excited towards wotlk when i saw all the changes coming.
Seeing other healer class geting new heals and abilities i was waiting to see the new spells and abilities of the holy priest.
I can say i'm abit dissapionted seeing all healer classes got new spells and abilities which by far upgrade them as raid healers. yet the holy priest gets no new abilty,
i'm very sorry to say: gaurdian spirit is far from being something that buffs the priest as a healer in raids or the raid in general.
This will make priests be the last choice in raid in wotlk: paladin who can regen his mana, heal raid and every 10 secs (holyschock CD) can casta instant holy light, a Druid - that can CR, inervate, now can also heal raid and has more healing abilities, shorter casting time on healing touch, and ofc the shaman: that wins with bloodlust, totems, "sharing dmg" leaving a HoT on who he heals - and ofc now a shaman can be really good at MT healing since he gets the Astral awakening (every time the heal with lhw and hw a spirit spawns that heals the raid, though can't understand how spirit has to do with shaman - spirit was always a priest thing).
so basically: all classes have the ability to be pro in healing every thing, but other classes also buff ithe raid in a noticeable way (since u can always take a shadow priest for stamina). the priest - that was uniquable by being able to heal the MT with HUGE crits, and at same time being able to heal raid quikly, now is just equal to every other class. even less - since the priest can't give BL, CR, anhk, inervate, blessing...
i call for a change !
