I've been working on getting my holy paladin up to snuff - he has +1250 healing, 99 mp5 with blesing of wisdom, 13% spell crit (base).
I was the healer in Heroic Sethekk yesterday and in both boss fights I had a lot of issues healing the whole team while keeping the tank alive. Whenever I had to heal just the tank or myself I was doing great, but once the whole team started taking damage all at once I could not pull off heals quick enough to get to everyone. I use Healbot so all I do is click-heal, but even then group heals were a chore.
I use mainly flash of light to top everyone off, and I usually use a "heal tank-heal a group mate - heal the tank again - heal another group mate - back to healing tank" sequence so that the tank is never too low on health. I try to avoid using holy light for group heals unless someone's super low because of it's longer casting time, and I use holy shock occassionally for a quick pick-me-up.
Does anyone else have issues with group heals and if not, what should I do differently?
