Why did you get rid of Walkie Talkie?

[Halo3ranger12]

I am having a very hard time becoming accustomed to the controls that have been laid out for us to play with. Could you implement the option for us to just assign our own controls ? I am playing on bumper jumper at the moment because it is the closest resemblance but the fact that A does not jump is a huge issue for me. So please Either implement Walkie Talkie as a button layout or give us the freedom to choose our own controls.

 

Thank you.
