The only thing that gets me wondering and raises questions is just how flip-floppy he is in his statements. In this one he stated that the game needs to compete on a global scale. Which means retaining subs, bringing in new players and keeping players happy. In another statement he said he's totally okay with people playing for a month, dropping their sub and coming back on the next patch...if they come back. Soooo which is it? Does he want a stable game, or a revolving door game? He stated several times about people getting bored, which should be code for "Heyyy maybe its time to change things up a little" but he's not, its all more of the same. He said he's trying to appease everyone, which is pretty much impossible. You can't appease everyone and by trying you create something that has no real direction. I feel that he's only trying to appease the hardcore Final Fantasy fan's and those that play simply "because its Final Fantasy" in hopes they stay till the bitter end no matter what. Which makes sense given how much the game takes from other games in the series, and story aside does nothing really to contribute to the series.
*Hey its Gold Saucer!!! Remember that from FF7?*
*Hey its Triple Triad!! Remember that from FF8?"
"Hey its magitek armor!!! Remember that from FF6?*
*Hey its Crystal Tower!!! Remember that from FF3?*
and so on and so on, story elements aside for the life of me I can't think of one memorable thing that that makes me say *Hey its XYZ!!! Remember that from FFXIV?*
As for character growth there are ways to accomplish it in a pure vertical system, but it depends on what players want. Are they happy with the current system which risks boredom after the raids and dungeons are done as well as older content being rendered useless over time. Or do they want systems that have say evolving gear, ability to enchant gear to add +1 +2 +3 +4 and so on to the items bases. RNG and grind heavy yes but does ensure players stay busy and older content stays viable for longer then a one or two patch lifespan.
