MAG is a deeper game than MW2, not only does MAG have a deeper tree which actually uses skill points but MAG also reaps the benefits of squad play through communication and planning, MW2 does not.
i just cant understand why some people think MW is the end all of fps, MAG not only kills it in size (in every aspect) but it ruins it in the using your brains department, it takes communication, team healing, team resurrecting, planning on attacks and defending, large scale map directives, leader orientation and squad reliance.
if anything the next modern warfare will take aspects from this game
