Forerunner & Crouching with radar and views

I am a huge Halo 2 & 3 competitive player. It kinda upsets me with the way 343 is turning halo 4 into. I am trying to stay positive about it but I think could still possibly enjoy the game. I want to see peoples opinion on the forerunner,since it is mostly going to be used in gameplay/mlg. I read some other posts about the radar only being able to work depend on the ground levels. My thoughts is that it could be a good idea to have it so when you are crouched you cant see someone in forerunner view. Believe me everyone I am not one to camp like a little noob. Trust me on that, I just think since we are going to know where everyone is at all times that there should be some balance to the game, and maybe they have another way of balancing it out.Idk. I just want to throw that thought out here and see what other people think…
