When I said graphics don't matter, I meant in terms of the current game. As in adding more polygons or increasing the texture maps doesn't matter when compared to just adding more content to it. If Square spent 10 million making the engine of ffxi look like ffxiv but didn't add any new content almost all of us would leave.
As I said, you can't have a graphics upgrade without them stopping work on new content, do you want more content or better graphics? You can't have both... unless you expect them to put a whole other team on making graphics upgrades.
Also many are vastly underestimating how much a graphics upgrade would cost for this game, mainly in terms of how much money people who do this are paid.
