Doubt it, simply because I would presume that would require the instance servers to be linked together as well - and one of the purposes of having separate logical data centers in the first place was specifically so that those resources would be spread out (remember Raubahn EX?).

I'd also like to see some of what little choice we still have of community partitions to play with remain a thing; the fact that "pile onto Aether" is such a popular approach already bothers me in that regard: it basically trends towards a community in which the hardcore culture gets to dictate the standards for everyone when it comes to getting a slot in an endgame party, while the more laid back communities are exterminated.

WoW has already shown the end result of this trend - I remember the days when someone behind the regional curve simply had to play on a similarly more laid back world and there was no problem. Now that it's one group finder pool per entire faction, so if you don't keep up with the national pace, you find yourself less and less allowed to even play the game (and preached at on Discord and forums that this is okay and you should just have put in more effort to keep up and are simply being the dreaded E word) until it's no longer worth your sub and you quit and pivot back to XIV.

At least we still have the option to travel to Crystal if we want a backwater. I'd hate to see that taken away by the Gilgamesh overlords as well (yes, I'm aware that not everyone who plays on Gilgamesh is like that, but it seems like players like that are permitted ever increasing power to control the entire culture of MMOs. Discord's platform policies are admittedly a problem as well, but that's probably another topic).

The sad thing though is that typically if you bring this critique of player pool mergers and its effects up, people talk to you like it's a good thing to forcibly hive mind everyone ...
