Well, for a bit of background of my experiences.. I was in Crystalline in FFXI for a long time, and eventually left during a big split due to some drama. It's a bit unfair to hold grudges and things of that sort, so I don't really feel much of anything as far as Crystalline in FFXIV, if that makes sense.
I just remember I didn't really find the leadership quality of Crystalline back then very favorable--and reading through people's opinions here it seems pretty clear that maybe some of that has stuck? It's hard to tell--I don't really like forming opinions based on other's opinions and all that.
To sort of go with Nox..As far as FFXIV goes--I haven't heard anything about Crystalline, good or bad thus far, just that it exists and a few people I know and were close with in FFXI are joining back up into it. I personally will probably not be joining, the story of it from the looks doesn't really fit well with any of my characters..Plus recruitment is closed anyway ^^. I have a few other LSes in my sights, but yeah.. From what I've heard? Pretty much nothing. From my older experiences? Eeeh..I'd rather pass..
