That said, with a personal CD, decent ability to avoid damage (displacer), and the Ysera's you'd rarely be in a spot where you are very low health compared to the raid. Means that other healing will (more often) be redirected to players without that many personal CD's. Worth noting also with the 10% health, Ysera is effectively 10% better than Resto Ysera.
You've obviously mentioned your own progression many times, so I'm wondering where Renewal can be considered outright better. Obviously Oregorger isn't one of them, as you mentioned you have only used it for farm, and of course during progress if you are trying to avoid the damage in P1 as well as frequently using Barkskin, you will take barely anything on that fight (and the small % damage you do take will get swept up with YG, so that brings up the "not wasting dumb-smart heals" portion). For a single bad acid torrent, you already have health pot, which means that to get your worth from Renewal you need to take a *second* bad acid torrent each phase which is less likely with a good raid.
Let's look at another fight, Maidens. There, yes, you can use 1 Renewal sub-20%, for 30% of your health. But YG will easily tick for over 5 times which is already more HP pool. Yes, the Renewal can "somewhat" save you from Death. But again, you already have Health Pot for that portion, so you're looking at *two* times you have to almost die for Renewal to be worth it. Plus every healer will be at maximum throttle (not a situation where no heals are going out), which means that your small ticks are actually adding to the raid HP as well.
I have not done Blackhand yet, but can agree there may be times CW can be attractive, especially if you are soloing Balconies. Whether it's really "necessary" or not (or if you have enough self-healing to deal with the Balcony regardless of CW), is another matter.
It's been discussed that many Resto Druids will take Ysera's over CW. Fact: Boomkin YG > Resto YG, and Resto CW is significantly better than Boomkin CW (since Resto CW benefits from resto +healing passives as well as resto mastery importantly). So, is CW really worth losing the DPS globals?
