Why can we only give out one player commendation?

He had to be kicked or we'd be stuck on tjat boss til time ran out

This is the situation where I do think there should be a kick option for incompetence. Unfortunately there's no way to implement it without it being horribly abused, such as elitist snobs kicking people in dungeons for not being iLevel100, or kicking people on DF runs that give the group a myth bonus.
But it's also something I wish they WOULD add...but only for the 24 person raids, and it initiates a vote from the entire raid. Because in CT, there are times when a full team is either staggeringly incompetent, or outright trolling the raid...and you can't do anything about it because they're not in your group. It's a really exasperating experience, as you're forced to choose between compensating for the dead weight, or leaving the raid and requeueing for the amount of time it would take to clear the zone.
