unfortunately though with Black ops the host advantage seems massive. I have a 20meg BB connection and it is very clear when you are host or not without having to look at connection bars.
Yes but it's always been that way, I see the difference all the time from playing at mine to trying my nephews connection were he almost always pulls host.
Cod 4 was the same, we would hook a bad host and go find a new lobby. It's certainly no worse for this than MW. I certainly felt the lag in that as much as any others. I remember our parties raging about the same things 'camping' 'lag' and 'killcams'.
I do though find it strange that in GRAW not once did I feel I was being beaten by lag in 1v1's. I was though on a better connection back then but I never worried about host or complained about lag deaths. I will be interested to see how the code stacks up for the new one online.
