i have started playing kz2 mp again as well. i just cannot believe how good it is next to mw2.
My only gripe with kz2 mp is the leveling up system. once you reach the highest rank, u have nothing else to go for.
I think they should change the ranking system where according to badges, medals and ribbons you rank up rather than kills and points. then they should allow a person of a certain rank to be able to issue commands or perform certain actions similar to mag. if gg would be able to implement this, kz3 will be all that and more!
p.s. and they should add just a touch bit more colour into it :p
