Mainly looking for tips for Halfus, but tips tank healing as holy in general will be appreciated too. My guild is not progressed at all, but we're trying to push it through specially with 2 friends coming to help from a more progressed server. Our healing comps are, according to them, horrible for the encounter (mostly shamans and druid) . They say a holy priest or paladin tank healing would make the fight incredibly easier, but I CANNOT FOR THE LIFE OF ME heal a tank properly in that fight. I've raid healed it without any problems at all however.
My current "rotation" is: Renew>Heal spam>Serenity+PoM>Greater Heal when Serenity and PoM are on CD>Flash Heal when they might die.
The problem I have is when either the healing debuff gets too high or the dragon breathes, I'm faced with a damage spike that makes me drain through my mana really hard (basically 2 Flash Heal>1 Greater Heal). This problem intensifies when the other tank healer cannot keep up with the damage, and I have to help him and then I'm either having my tank dying or just wasted mana. Is it my responsibility to heal the other tank or should I just focus on mine?
Pity that MMO still won't let me post links and you can't check me out on the armory. As of now, I've only thought of 2 things that could help:
1. Reforging everything I reforged to mastery to haste.
2. Get Glyph of Flash Heal instead of something else.
Any help would be really appreciated.
