The only thing that would make me unsub is instance housing. And no, not in the bad way. Meaning I could always log in whenever and see my house is still there (kinda like how we already do in xi regardless of time passing) and really only come back when there's new content available for msq, hildi, raids/alliance, and relic weapons. I really only keep my sub and log in every sunday (going inside my house and sending retainers out). If they made instance available, id freely give up my house, get a portion of my gil back, buy an instanced house, and unsub till next series). Otherwise, I have no reason to log in atm.
