In some long fights i have problems with ooming. ive read a lot about priest and ways to help. people are saying you shouldnt need to use flash heal or prayer of healing but for example in VoA on the frost boss, when people get hit with 3 stacks/ white out, all the raid is below 1/2 hp. i can only use CoH once every 6 sec so i use it on one group and spam PoH on the other groups to get them out. When there is Aoe, i find myself using PoH all the time when CoH is on CD. Should i be doing this? or should i just spam everyone with renew or just FH everyone up while PoH is on CD?
Is the reason i am Ooming so much b/c of PoH spaming when there is AoE damg? or is the the fact that i might have kinda low mana and just need better gear?
