This is exactly why I don't like LFG as Bungie's answer to the lack of raid matchmaking. As we found out in the Great Gjallarhorn Controversy of Year 1, there's way too much arbitrary kicking, and too many people only interested in taking what they perceive as the easy way out. I don't really care how people play the raids in general, but I think it's a shame that in a game like this, that can be so much fun when people work together, people do this kind of crap.
