Depends.

Either waiting for 8.0 while not being subbed if it hasn't released at that point or two possibilities:

1st: 8.0 is not a disappointment, story is good and they fix enough grievances I have with the game, content and so on. That would mean I would probably play FFXIV.

2nd: 8.0 is disappointing, story is meh or bad again and they fix nothing that needs fixing / adressing / improvement. In that case I'll uninstall FFXIV.
I give them till 8.0 to get their shit together. If they don't wanna I am gone.
