I've been hearing the same complaints about spawning since COD4. People complained about being spawned into an airstrike, claymore, heli path all the time in COD4. They also complained about how the spawn system allowed teams to get backed into corners with no way out. In Crash, for example, you could back a team back into one of the original two spawn locations. This was true for all COD4 maps.
When MW2 came along, people complained incessantly about opponents spawning into areas that were just cleared or even right behind you. All of which was entirely true, and entirely frustrating.
BO isn't any different. With every game comes a refresh of the same complaints, but things always look better in hindsight.
Truth be told, I don't have any problem with any of the games' spawns, though I preferred COD4's because it allowed for good teams to control the map. Note that COD4's was the most unrefined system of them all, because they took deliberate measures to kill this phenomena in MW2, because most people bitched up a storm about it. Likewise, go back back through the MW2 thread here and you'll see people complaining about bad guys being spawned from their "loins" and "assholes". MW2 was notorious for having people spawn right behind you.
No offense to you personally BD, but it's funny when people look back and say "oh that game was fine." Everything you're saying is wrong with this game's spawn system has been brought up with every release since COD4. None of this is new.
