The general player base needs to improve

[Gallus]

The goal isn't to turn someone into an expert in 5 minutes. It's to take someone who is having trouble with something and help improve it. That can absolutely be done in chat, from first hand experience on both ends of it. Doesn't always work, but sometimes it does, and that success rate is far better than throwing your hands up and declaring it's hopeless so why bother trying.

Personally, I don't offer advice to anyone unless they explicitly ask for it or unless someone is blatantly wiping the party with a very specific mechanic. Calling out someone in a group automatically means you are telling them they are doing something wrong, and not everybody takes that well (especially because when that happens you automatically are setting the focus on them, and understandably, some people feel uncomfortable with that). More often than not you'll be meeting with a bitter response or an unpleasant silence, but let's not pretend this is exclusive to FFXIV... this literally happens in every online community and even in real life in general. If you are telling me you can deal with that and that you rarely kick anyone and rather finish the dungeon and move on, then I don't see a problem here because this is as much of a big deal to me than it is for you.
