Lagging Players out of Horde Mode can't finish a full 50 Rounds

I am getting Really Upset that Horde Mode is Lagging players out in Quickplay Horde Mode and Everytime i play this game Mode Players start getting Server Lagged out and it’s really Upsetting that I am always being forced to Leave at Round 38 because of Server Lag and players being Lagged out.

Please Fix this Issue I am Upset.
