When you attempt to please everyone you please no one and this thread is fantastic example! Appealing to majority of self entitled babies in adult bodies never ends well.

First the "elitists" evacuate to form their own groups to clear content that becomes less and less satisfying then leave once done.
Then the "average" player grows weary of being shouted at or expected to carry the below group and leaves. They may or may not attempt end game content before doing so. When they do, finding a party is one exercise in futility because group A left already.
This leaves group C, the "toxic casual". Group C believes that everyone is okay with dragging them through content and across the victory line kicking and screaming. They often lash out at others as children without understanding would. Groups A, B, and even C do not wish to play a game with group C (no matter how much they tell themselves they do).

Once groups A and B leave the game only group C remains. Group C proceeds to devour each other until everyone is sick of playing and the game begins the downward spiral into oblivion. FF14 has already reached peak levels of group C, what happens next will be most predictable to anyone with working brain cells.

Look towards a game that appeals to groups A and B, Dark Souls. It still has a fairly active community of friendly players despite being very very old and riddled with issues and bugs with netcode so bad it puts FF14's to shame. Heck! I have had invaders treat me with more respect and dignity then 50% of my duty finder groups and their soul purpose is to kill me..
