Posting me two bits, then will read into thread.

I think two things that went against FF14 and still trying to salvage are:

The original design based around turn-based combat in an MMORPG, thus involving slower paced combat. Battle regiments were built around the original design and don't seem to fit well with the present design.

The interface missing common MMO concepts, such as being mouse friendly. Can be expounded upon request.

The problem now with tinkering with the system now is how to change the core of the game and still keep all the players' progress? And what amount of conversion of your past efforts will transfer to a revamped system?

Innovation of the JRPG is what I know Squaresoft for. And I still salute them for their more international approach at FF14, their ongoing efforts with the game, and their consideration for their nation during these times.
