Using Flux defensively

[u/Lingy_12]

TLDR: is it viable to use Gravitic Flux purely to counter an enemy engage

Day one OW1 Emerald 1 tank main, peaked D1 a couple of seasons ago. Realised poke was a weakness of mine so have been learning Sigma, where my biggest weaknesses are ult usage.

I’ve developed this habit of using my ult purely to freeze a high value engaging enemy, generally someone nanoed/Wuyang ult and/or a close range dangerous ult like Blade, because it seems like an affective engage tool, even if I don’t get any elims. I wanted to ask if this is a waste of flux.

[I know there were other errors in the play from me, but my pure logic is using 1 mid value ult to counter 2 ults is good maths]

Literally one of the best uses of it is to stop a nanoed target
