Why must they say hello or hang out with you for 3 more mins while you finish your hulu show? People join for their own reasons, most of these reasons are enablers for another task: soldiery farming, zodiac drops, etc. Efficiency then becomes the main motivator, as completion of the dungeon is not the end of the task, merely the step.

Honestly, if you want to change behavior you have to understand what is enforcing the behavior. Grinding is enforcing this behavior. You cannot change the stimuli, thus you cannot change the root of the behavior.

Trying to do it will just frustrate you. And it will only aleniate the community from each other, like how this topic never fails to polarize the community almost as bad as political affiliation.

So compromise. There will be groups more reasonable to your pleas than others. Enjoy them. Truly. But there will also be others that will stress you. And in those I refer you back to trying to create constructive or positive change.
