League Play was a colossal failure of a gamemode and this by no means was the developers fault. LP only proved that nearly everyone in the community felt they were the best player in the history of CoD and when they were proved otherwise they quit.
I never finished a round of League Play with everyone still in the match by the game's end. In Masters, Platinum, or any other ranking.
If you are referencing League Play, you might be referring to the information provided by Teanah (IW Dev) in this thread: Upcoming improvements for Ghosts eSports (1/16/14)
- Add eSports rules to Clan vs. Clan playlist.
- Open Clan v Clan playlist to allow solo player entry & mixed clan teams.
It's not League Play, but it does apply the recognized competitive ruleset to an existing playlist.
League play? Is that the mode where you played 4v4 (Or the 6v6 one which was pointless) on some of the worst modes imaginable (Hardpoint is meh, I suppose)? where you needed full team co-ordination for anything to work, and the moment anyone ragequit you were ******? The mode where unless you were a truly remarkable player, needed a full team who knew what they were doing to get anywhere? Yeah I remember that.
