You gotta be kidding me with this crap. I take it you have not played CoD4 recently? Do it, please, it's like night and day. Lag comp and latency issues in BOII isn't just something people who are bad at the game complain about because they suck,
I'm not saying it's that. I'm saying that a lot of the time it's an issue of someone playing a game where host is notably further away than optimal. If you are in a game that already has 150+ ping and you aren't host, don't get your hopes up.
Please list which stages spawn logic isn't a problem on, because it is on a vast majority of them.
The only stages with truly problematic spawns would be Raid, Hijacked, Meltdown, Carrier, and Slums. And nuketown too, but that's because nuketown is the second worst map ever created.
Raid's problem has mostly to do with the game liking the garage spawn a bit too much. They might be able to fix it by having the spawn logic a little more biased towards the areas next to the garage.
Meltdown has a similar problem with the spawn side of the map with the slope. Might be fixable by having players spawn in the room next to said slope or the open area to its right.
Hijacked is a shitty stage in general with not enough rooms. They could start having people spawn in the basement but such a thing would likely lead to spawntrapping people in the basement.
Carrier is just a bad map in general. It encourages sniper spawn trapping and has all the problems of an MW3 map and cannot be hoped to be fixed unless they were to add more junk to the middle of the map, which they aren't going to do.
Slums has the issue of not having enough rooms on the map. Another issue that would require them changing geometry to the map to fix, which we know won't happen.
Drone, Standoff, Express, Aftermath, Overflow, Plaza, Turbine, and Yemen all have fine spawns.
So there are two maps that have spawn logic which could be tweaked a little. The spawn logic complaints remind me of MW3 where people had the dumb idea that the spawns actually could be fixed on maps like mission and dome that didn't even have areas designed for safe spawning. Hijacked, Slums, and Carrier and not fixable maps. Get over it and instead ask them to fix shit that actually is fixable, like the uselessness of hardwired.
