I never get fully burnt out enough to ever unsub but I tend to play less and do like bare minimum to get my weekly caps on things such as logging on just to do Roulettes for the day. I'm mostly waiting for Stormblood to come out so I have a ton of things to do again. I've been investing time into PVP though more than any of the PVE content but that's mostly because I want all the Garo stuff.
