You are lying through your screen. I have never even been or seen someone spawn killed more than 2 or 3 times in a row and that is when I/they would be getting spawn killed by a choppergunner on nuketown. NO WAY IN HEII YOU GOT SPAWN KILLED 6 TIMES IN A ROW
Due to overpowered killstreaks such as reapers, ac130s chopper gunners etc on pervious CODs the spawn killing was much worse so it is kind of ironic that you think it is better to play one of those games.
