An e-mail from HMS to a fan. "Regarding Killstreaks, we had them in for a while during our dev of the game, we took them out for balance reasons. Let me explain, every game has a very unique MP pace and with all the changes from WFC, what we were seeing was runaway gamers, specifically due to killstreaks. By removing them, they game was more competitive. Along a similar vein we removed double jump, many gamers initial reaction were negative until the played it for a bit and realized that the streamlined approach actually made it better. remember this isn't WFC2 this is FOC."
