(1) From XIV beta - Journal customization -Scheduled for 2.2
(2) From XI - Chocobo Breeding - -Alrdy said in Development
(3) From XI - Gardening - -Also in Development, but only Gysahl Greens thus far
(4) From XIV/XI - Ferry and Airship options.... to choose between doing the journey the short cut way with cutscene, or to do it the long way to fish and find NM's just like in FFXI
-^^ Interesting Idea, but doubtful

(5) From XI & XIV beta - Open world NM's with rare/unique drops. -Unlikely Since FATES are the new Open World NMs/HNMs
(6) From XI - Personal Bazaar - Also Unlikely due to the mass disapproval of it in 1.0
(7) From XI - Robust Auto Translate with full JP input. -Would like to see this as well
(8) Ability to have Minions in Dungeons -A hopeful change I would like to see
(9) Have the facility to do a Name Change -I believe they are working on this to be input to the MogStation
