That's fine dude, do whatever you like. That's why we have the vote to kick option as well as a leave group option. As I said, I go with the group. If they spacebar, I do. If they watch and I have time, I will. I understand the anger you feel when being told what to do...I dislike that as well...but I take action when something like that happens, I don't whine on the forums.
Do you not see the incredible arrogance and selfishness or using vote to kick if someone won't deviate from the normal method of playing a flashpoint. If you feel you need to leave the group, sure. But don't be a jerk about it ans try to get them kicked. That's just not cool.
