I expanded my earlier post for easier reading of the main points in the feedback. The threads contain comments from other people as well but many people I've talked don't post on the official forums at all. Ever since Stormblood I started being more active in the theorycrafting community and got to talk to a great many people suffering with ping problems almost daily. I've been trying to be a spokes person for them and put a lot of time in my feedback so I hope that the developers would take notice of it eventually. Many players will simply give up on the classes that require good ping and never play them, they might even quit the game because they can't play it properly and you never hear about them so the problems stay buried.

If anyone has been following the Media Tour information, even Mrhappy1227 commented on the weird lack of changes to help with the ping issues in his MCH video on the changes. Some other classes did get changes towards "stressful" abilities, but it seemed to be based on very arbitrary feedback since it didn't extend to all of the tight windows or abilities. The video can be found here: FFXIV Endwalker - COMPLETE MACHINIST Changes & New Skills Overview. By the way, initial theorycrafting seems to suggest that MCH weaving will become even more stressful in Endwalker. Please look forward to that.

I really hope SE can start looking into the animation lock systems and do something about weaving. If the problems can be greatly alleviated by 3rd party plugins, surely the developers can do something about it as well.
