The campaign is good for immersion into the story line, multiplayer is about consistent and balanced gameplay.
Your entire rant is null and void because you don't understand what makes a good multiplayer. Halo will not be copied for the next 3-5 years since they've literally copy/pasted half of the gameplay features from cod. It's dull and unoriginal, and instead of halo taking up 90+% of my gaming time, like previous titles, this game will be lucky to get 30%.
The campaign is great, spartan ops is fine, matchmaking sucks.
