Did you know not performing as you think another player should in a group

[Reynhart]

And if you were to not count the initiator and the individual up to be kicked, then kicks could be avoided altogether by pairing up with a friend.

Yes, so ? You'll pair with a friend and troll the other two people ? For what ? Last time I checked, if you tag for an instance and just good around, you'll waste both your and your friend's time.
And if you can't kick everyone on a whim, maybe, just maybe, people will actually try to behave a little better if they don't want to waste their own time.
