All of the comments here are interesting. As a tank, I stepped into Stormblood with a focus on Tenacity. Of course, I'm always questioned why I do it.

In a post some time ago, I noted that healers were having a grand good time doing more dps than healing me. Looks like Holy and Gravity are still beast on the aoe, more than my "Total Eclipse" and "Quietus".

I removed Tenacity and am trying the Direct Hit thing, and I find myself needing that extra healing from Convalescence (I didn't use it much with Tenacity). I don't have access to much Tier 6 Tenacity materia now, but I will be going back to Tenacity, even if I have to meld Tier 5s until I get 6s.
