New 80 Disc Priest, Cata Dungeons/Heroics/Raids?

[gokuweeddad]

I've leved a Disc Priest from 15 almost exclusively through LFG. I really enjoy healing and have experienced no major problems, but I'm hearing that Cata dungeons really step up the difficulty. Shouldn't I be able to just go in and heal like I've done in all the other dungeons? Is there a priest healing guide for Cata dungeons/raids? Thanks!

Priest healing gets rough at level 84. Your spells will not get stronger but their mana cost will spike. Level 80 mana regen is not balanced, it's almost overpowered so that is little comfort.

My priest is level 81 and i as well leveled mainly through LFD. Healing and mana effiecency seems much much easier now compared to when Cataclysm was released. (I leveled a resto druid back then). I never have to drink, my mana never goes below 75% I actually kinda missed how it was back when Cata was just released. But like I said im only level 81 on my priest so I assume it will be much more difficult around the 83-84 levels
