I DON'T like Stormblood RDM

Preventing wipes in dungeons when the healer goes down.
Preventing wipes in 8 man content when both healers are down.

I see these happen quite often and would not call it "niche"

I get that the very top end is concerned about the impact the rez makes on the maximum dps you can eek out but would rather that you focus on other methods to fix that imbalance than take away a utility that the non savage raiding majority find very useful and helpful.

Preventing wipes in normal mode content is meaningless, in Savage mode, RDM can only save a run of a really good group during progression for at least the first 2 and maybe the 3rd depending on when someone dies. week 1 titan wasn't possible with a death and RDMs were switching to BLM because of it. your niche has alot of flaws that come from just looking at how the game performs in the content that jobs should be balanced for primarily. nobody needs a job that can save your normal mode run

It's all meaningless.
