What makes it any clunkier than a Intervention/ Blackest Night/ heart of Stone/ Shirk macro?

Intervention isn't used often, same with shirk, 2 minutes is a pretty long cooldown and you usually do it every 3-5 minutes. Blackest night and heart of stone can be used on yourself. Nascent flash NEEDS another person for YOUR OWN mitigation, that's what makes it clunky. Not only that, but since it's a 25 second CD, you use it often and can fumble quite easily if you are unprepared.

You're not wrong but I find trying to use it in the middle of a fight manually is also kinda clunky. And this is coming form a former DRK that often tried to throw out TBN on characters with damage taken up or low HP from a coming Raid hit. In part due to it possibly not being needed? Oh the 10% damage reduction for them is okay but most the time the healer(s) are also going to jump on that drop of HP as well. And if I need the HP? Well Equilibrium is still sitting there.

Personally I find the short duration to be really annoying to try and quickly work in what attack(s) I need for the HP as well and if I'm that low to need Feel Cleave HP, again the healer(s) are also probably jumping on me in which case I'm probably popping Thrill of Battle.

Now Nascent Flash seems to be just okay to niche for me. I'd rather just pop Raw Intuition but I don't do EX/Savage so maybe it sees better use there?

You can easily prep a fell cleave or two for nascent flash and even if you get like: eye > upheaval > fell cleave > heavy swing, it will still heal much more than what raw intuition will mitigate from autos, even on E4S where Titan autos for around 30-31K.
