What makes you think it's more like BLOPS? I was never a huge MW2 MP fan because I sucked at it but I loved BLOPS, more so when I moved to 360, as it suited my gameplay style. MW3 plays exactly like MW2, mostly because it is just MW2 slightly tweaked and with new maps, and whilst I don't hate it I still prefer BLOPS over it.
You've gone down in my estimations son. Blops was decent. The only thing that kept me playing that was the banter. It is nothing compared to MW2 & 3 though.
