YES!!!

Last day, we had a tank that said he was watching a football game... so he started to autofollow the summoner... and said that I since I had titan egi... I didnt even needed him...
He made us solo the dungeon until the boss.
I admit when he did that we raged at him... later at the boss he said he wouldnt even move.. unless the whole party apologized to him, and if we wanted to finish the dungeon we needed to apologized to him....

Horrible experience... I made a ticket to report that guy...

But yes we do need this feature now...
