They need to find a way to detect XIV Alexander and ban people

So, you are against everything that makes it easier for players to do stuff. Are you then also against all these fan sites that are out there? Who help you create crafting rotations or show you the most efficient route of gathering materials? Who have timer for gathering nodes or FATE spawns? Which use math and probability to "solve" cactpot?

Because if you are not against them, you are a hypocrite.

I'm not sure why people think that having an overlay is somehow fundamentally different than, say, a picture-in-picture mini-window of the website they're borrowing crafting rotations from. And, as you said, if the latter is permitted...

Its not even about that, cheating and modding, makin things easier as theyre supposed to be gets us to a point where you either use it or be left behind....

There's a difference between a plugin that shouts at you which mechanic is coming next and one that simply makes your UI something you can stand or that allows for better PF filtering, prevents getting booted over certain types of lobby errors, corrects netcode as not to doubly punish players for their ping in attempting to double-weave, etc.

The prior is a cheat and yes, should be prevented; the latter is the community picking up the slack for the dev team.
