i dont think theres a big need for them really and the only one i found usefull was on radiation

I like the ones that added strategy. Like Stockpile and Radiation. The guns on Berlin Wall were a great place to throw care packages. Especially during DOM. People would focus on how to get those rather than points. Same on Jungle I would throw my packages into the minefield during DOM to distract the other team. I would like to see more interactive maps.

Yes for interactive maps. It helps break from the boredom.

Example, in a party of about 4 people in TDM. We all went down the zip-line in Kowloon at once, and we died some many times, but both we and the enemy team got so many laughs that it was worth the losing game. XD

So far from what I've seen the MW3 maps don't look too interactive. I think because most of the current maps in MW3 on focusing on cities rather than secret bases and wutnot like Blops, there is a little less to do, but I could be wrong.

I want more silly easter eggs to be honest, like The Rolling Stones playing in Nuketown. =D
