So I haven't actively tried to tank since I hit 50 and cleared Ifrit HM (as OT, I was bored out of my skull during the fight, AND had a better geared BRD anyways). But I've recently been hearing/seeing tanks use flash or be told to use Flash 3-5 times after the initial pull. Is this how it goes now? Has something changed? I don't remember needing to really use it more than twice on a pull at the worst before. And IF anything slipped away from me, a quick provoke/shield lob or RoH was enough to get it back.

So if anything, I just want to know does it really take 3-5 now to properly - initially - generate and hold enmity? Or is this a widely-accepted but overkill method?
