If anyone says the awful words "blink tank" I will personally come to your house and... paint your room bright pink and force you to watch Justin Bieber concerts. j/k :P

Seriously though, blink tanking was one of the worst parts of FFXI, as the Job was never even designed as such - Utsusemi was a minor ability for NIN to allow them to get out of danger fast if they pulled to much hate, but of course players being what they are, abused the mechanic and made it a form of tanking - the fact SE took ages to adjust the Job to reflect how players were using it only shows it had not been their intention. I really hope SE never brings anything even remotely resembling blink tanking into FFXIV, as I will quit the game otherwise.
