Just to bring back on topic, I agree with the OP on set bonus 3. Seems like they need to bump our set bonus a little - ok, ok.. a lot. I'm not saying it has to be completely even, becuase theirs could still time out (not likely on a raid, but that's beside the point).. ours heals for greater per tick, which IMO is a tad more valuable. But the difference in overall healing needs to be narrowed.
For set bonus 5, I'd personally rather have the bonuses to aura. A "up to 50" bonus to healing spells doesn't currently seem to add up to much since they are capped to a max benefit based on the heal amount and/or normalized to 3 sec cast time. I think my "up to 40" bonus from an adornment added like 6hp to convert, which is just lame. I get somewhere less than 40 on my small heal as well, because it only takes 2 seconds to cast it.
