huh what
cod =/= halo =/= blacklight
seriously they're so different it's not even funny.
blacklight is MMO because of the way it treats the servers - you get a list of servers along with a chatbox rather than matchmaking, and halo and call of duty both do the latter.
I don't really care how different they are
CoD does have a server list, and it does have a chatbox (goes to show how much you know about what you're talking about)
having a server list and chatbox doesn't make something an MMO
do you even know what MMO stands for? I wouldn't be surprised if you didn't
