You get crucible rep(or whatever faction you have set up) and crucible marks(which are needed to buy iron banner gear anyways) so you are getting something. You are also getting a chance at free gear, coins, engrams, shaders, mats, etc. Your actually getting a lot. Not everyone deserves to get something. That guy who went 2-15 and made us lose shouldn't get prizes for doing bad. It's a team game. If I play baseball and we lose the game I don't expect a trophy because I scored and my teammates didn't. I accept the loss(and potential other free stuff) and move on to the next game where hopefully I'll do a little better and get a better team.
