If you add a shared sub model between XI and XIV

[Alhanelem]

Likewise, since XI is not a fully instancef game I'm not going to be happy if I can't do anything I log on to do cause it's full of people who are getting it for free due to paying for something else.

1) they're not getting in for free, they're getting in for a discount to offset the fact that it's hard to simultaneously play two MMOs. if SE charges (example) $20 a month to play both, that's a modest savings for the buyer, it isn't "for free," plus they can still pay the extra dollars for more characters and storage.
2) Unless you're on Asura, this isn't a problem and the impact of such a promotion, as I've said many times in the past, would be nice but it would not be enough to create such problems where they don't already exist.

An incentive to play both games can only do good for both games. There is no downside here. I'm not so sure I'd be paying for both if I didn't already have the XIV legacy account discount. If they did do something like this, that just means other people can enjoy what I'm already enjoying.

We've been through this multiple times and it's pretty apparent you were trying to bait me, well you've succeeded, so congratulations I guess?
