Simplicity over complexity, time to change.

[Felessan]

It's time to introduce the hybrid role Yoshi mentioned once, specialized stats, dangerous open world, more and better character personalization, horizontal gear progression(keeping the ilvl system, some players seem to like it)...

We don't need another FF11, much less 15 years old outdated design practices.
And honestly nothing you mentioned will be implemented. The world belongs to people, and people in this case is a casual crowd. Those that doesn't really likes being locked out of some zones, run half an hour to a point (nobody but rare minority actually likes this) or having 20 sets for each class where only math guru really can understand what is better and when.
The game kept simple to be more accessible for everyone. And for hardcore there are things like coil, ex and now "professional" hunting.

. QUALITY is better than QUANTITY. I rather do cool moves once in awhile than a flashy attack every 3 seconds.

FF11 combat have nothing to do with quality. It's just boring oldschool, very outdated, design. FF14 combat on other hand are quite tactical and technical, this is why such MMO called "theme park". You don't really need a complexity to make something really difficult to master and board games like chess and go prove it.
People en masse likes concepts that wow popularized, like easy travelling, full access to zones, straightforward and easily understandable stat mechanics.
