Season 6 is a Code and Tech update with the bonus extra events thrown in atm, the main content updates and additions are, have been and will be available closer to Season 7, which could be as close as September or November in release from my release sched experience.
Prob around mid to late august we will see more info on Season 7 as Content is smaller branches of code additions compared to the Season update.
Yeah... I burnt out after grinding constantly to try to get my XII set on a single character (one piece away).
They've talked about how XII will go to EDC's, but now they are going "Oh, it's way in the future."
That'd get me actually... interested in playing more. I'll see what the Season 6 changes are from an ingame standpoint but I'm not too expecting to be playing lots even though I have a character or two in fleets (cause fleets sound like an all or nothing deal if you want the new stuff for yourself.)
