Living Spirit @ 400 Base spirit returns 5mp5 in combat. Hardly worth the 3 points.
I'm currently Dreamstate spec, but after seeing 25man content and the lifebloom buff next patch I'm definately going to respec full resto.
Swiftmend and lifebloom is something only the resto druid can bring to the raid, whilst HT spamming may be effective - it's something both paladins and priests do better.
1280 +Heal seems a bit low for someone geared @T5. Your probably missing out on alot of enchants, or have some sub-optimal gear. Currently I'm just entering SSC and am +1503 base heal unbuffed and untalented.
