I total agree with you about the spawning system on this game. Its as bad if not worse than every other game in this series.
On the other hand i havent been disconnected from hardly any games. In fact ive only been disconnected from 2 games in over 980 games so far. So at least its heading in the right direction
In terms of Lag........Ive switched from having a wireless connection and plugged the PS3 in by ethernet and it 'seems' to have cured the problem i would say at least 80% of the time. Although there are still games that you can see that there is massive difference from what the killcam and what you saw on screen.
When i got the game at christmas the lag was horrific and i was pretty much on the verge of trading it in (Both Wired and Wireless). But for myself lag seems to, for most parts, been cured by plugging the PS3 into the router by ethernet
The spawn system combined with the lag is the biggest problem with this game in my humble opinion.
I don't know how a BIG studio like Infinity Ward doesn't learned with their mistakes. Since MW3 we're complaining about the same probs... I just don't know why 3arch can copy things from IF games, while them refuse to copy things from 3arch games just for improvements.
That's so sad.
