Is there a reason a hefty chunk of SCH heals are unaffected by buffs

[Krovoc-The-Destroyer]

With 4.1 coming out, and no fix to this in sight, I thought I should ask if this is intentional or an oversight.

A fair bit of the healing I had been putting out as SCH pre-SB was from Lustrate, but most of it came from some sort of spell-based sort, so I didn't really care too much. However, now, with the nerf to Embrace, and the addition of Excognition most of my heals are coming from abilities as opposed to spells. WAR/SCH pairings were a bit troublesome before for this reason, since Defiance's heal buff does not affect Lustrate, but again most of my healing was coming from spells so I didn't care too much. I wouldn't call it truly problematic since I've never been in a situation where I was in any serious content with a pair of warriors and another scholar (WAR/WAR +SCH/SCH), but it is still an issue that seems like it needs addressing. To add insult to injury, we now have Largesse as a role action, which does nothing to boost ability healing.

I'm happy to see Succor's shielding increase, this was a sore spot for me, but the MP un-nerf from Adloquium seems unnecessary now. I've never really had issues with SCH's MP before, so it seems like a wasted jesture (pun intended) when what really needs to happy is a change to how Largesse, Defiance, Fey Illumination, and the other similar buffs that I can't think of off the top of my head.

So, is there a reason for this? Is SCH unbalanced otherwise? When one tank/healer pair is so much worse than another, that doesn't seem like you're balancing anything.

edit: In general, I'm satisfied with SCH kit, it just that there are some significant disparity in some cases, most significantly 4-man dungeons with a WAR tank. This seems to be a significant balance issue since healing a DRK or PLD as SCH is largely trivial in these dungeons, but a WAR is actually a bit of a challenge if I actually want to get DoTs in. To clarify, and give a concreate indicator, if the tank is a WAR, I can barely get DoTs in. Sometimes, if that tank isn't geared as well as I'd like, I can't even get all my DoTs in. Otherwise, with the other two, I'm spamming Broil II.
