I'm more and more for this bug-reporting software solution. This has been asked about a gazillion times so it's the perfect example to why we should have such a solution.
Back on topic I agree, the radio commands are just a comm-tease for now. I am extremely excited to see what kind of AI programming we'll have in the future
Already seen the AI-skill sliders ingame and I hope these will have a greater impact on gameplay
Also the ability to destroy one's radio equipment will render a plane isolated from the communication. An ability to switch frequencies, and turn radio on/off would be cool seeing that a destroyed radio might just spam a lot of static noise :p
