Which I can understand, off healing is just not a roll I am asked to perform. Soaking mechanics, etc, is a given though. Are you 10 or 25 man? 10man I can understand getting most out of a HoTW tranq-less so in 25.
It's been a DoC tier (minus spoils and gala) for me pretty much all x-pac. If anything our healers always complain they have nothing to do and I've been 14/14 H for a while. I guess it's just a difference in raid styles/leadership. Even during progression I didn't run HoTW, it wasn't needed.
I have nothing against throwing heals on myself to keep myself alive but clicking all over my raid frames to spam rejuv on the raid is silly imo unless there is downtime or your forced away from the boss. While its nice to have the ability to do so-If it can be achieved while performing optimally-great, If it can't? No thank you here.
