We are now halfway heroic raiding, having fun on the way. However, on my personal part as disc healer I am having less fun. With disc I feel pigeonholed into a supportive spec that is only viable when a) a lot of people get a lot of damage (and even then, others healers dont sit still) and b) we have 'main' healers able to tankheal and spotheal. Our healer team changes a little per evening so b) is not always the case.
When I need to tank/spotheal, that requires in the end to shadowmend a lot. Because via atonement/dps is clunky. By the time I plea/shield and start dps, another healer often has patched them up, and often tanks take too much damage for that approach. And on the Eye for example, I am too slow; two eye 'zaps' and someone is dead, so spam shadowmend is still better.
However, shadowmend means spending too much mana... catch 22/2.
The only place I really feel viable is in 5 men. Maybe I should start investing in holy? Or am I missing something?
(And to emphasize: we are not a mythic team. We are a stable heroics team, with varying attendants per raid.)
