What's the point of CSR if we have JIP???

I’m getting really frustrated by games where I’m trying to rank up, but I get a join-in-progress game and either my team is down by a substantial amount, or I can’t be individually good enough coming into a game where some people already have 10-15 kills to actually do anything, so I rank down. I don’t like using the “my xbox 360” thing everyone talks about because it’s honestly a hassle that is completely unnecessary.

Please, 343. End the JIP madness, stop in-menu quits, and bring back a veto option…
