i think in 7.x they need to return and work on "forgotte" systems in place of new one

Finish up the ranking system of Squadrons or give it a re-work for current day FFXIV.

Return the removed PVP maps back into FFXIV that was taken away over the years.

The Chocobo Companion System, update to its combat abilities & remove the requirement of Thavnairian Onions since people been gil abusing others on the market board.

Decrease mechanic timers for all monsters across all current wilderness areas from ARR to EW including regular FATEs, as they are now they're way too easy. There is no point for these monsters to have mechanics if you can just simply dodge it so easily because of the long winding time for each creature to use it. The only time you'll ever be hit if you're literally role-playing turn-based combat by allowing yourself to stay within the cone, AOE or etc. I don't recall other MMOs having such a inbalance issue.

Increase Tribe Points from ARR to Shadowbringers, due to the amount of tribes now I think players would want to catch up as much as they can to do current content.

Other things (not really related I just want to throw in here):

I uh...I still want the ghost hotel from FF7 be put into the Gold Saucer, I want a creepy hangout spot. >.>
