If Terminal shows up, leave the lobby and join a different one. Keep doing that, it's what I do.

simple answer as it was causing a major matchmaking issue.

by having the terminal dl as optional they created another fragmentation of those with it and those without on top of the usual fragmentation caused by usual dlc drops

easiest way to fix it was to make the terminal dl mandatory.

WOW, moaning about a free map, people these days lol

It is quite stupid that you have to download the map in order to play with the others. But, seeing as how it's IW and their match making is the worst, doesn't really surprise me much. I mean, these talented developers are the same people that create logic that puts you into games where you're placed on a team getting raped 60-12 in KC and then punish you with a loss if you decide to back out. And, my personal favorite, being put back into the same lobby/game you just left 3 times in a row.
