My spawns are perfectly fine and I get like 1 laggy game out of every 50 I play. I really think you guys are just having a harder time doing good in Ghosts so you look for scapegoats to blame your bad play on.
I wish I had a cap card so I could video tape my play and show definitive proof of how little spawn killing actually happens. Out of 10 games I get spawn killed 2-4 times MAYBE.
