FF14 is not made for hardcore players.

We can judge though, it’s an MMO. There is a bare minimum asked in all fights based off an enrage mechanic and it’s implied that you can at least meet this or be open to criticism/suggestions. The casual-elitism is thicc ;p

No actually, there are no game rules set by the developers that state people who don't meet the bare minimum should be open to criticism. That's nonsense. If someone is making your DF group (please notice the big DF here) a mess, you have three options as given by the game's mechanics:

1. Leave the group.
2. Initiate a kick.
3. Persevere and finish the dungeon.

You can offer the option of help in a nice way too but only when the time is right together with the circumstances. Notice the "option" to help. I am not talking about unsolicited advice here.
