I'm not really sure where the best place to ask this is, but my roommate has just recently begun playing. However, after he and I played four or five custom matches together against AI for him to learn the ropes, I noticed he wasn't covering the points I told him to go to or when I asked for help without pinging, he wouldn't respond.

I realized that he had been rotating his camera to an angle (at a similar height to the default) to be behind his lines. Like the map is either a perfect square or rectangle and he has his base at the bottom. He is convinced that he sees more of the battlefield, whereas I believe he's blatantly not seeing things on his flanks as well as he believes. The other issue is communication. When the terms right and left can't be agreed upon because he rotates his angles, communication becomes an issue. I don't mind adjusting my descriptions of positions, I just am concerned that he's impeding his development.

Does the camera angle make a difference at all? I noticed I had a decrease in performance, but couldn't concisely explain why I think the default angle is betters aside from "It makes communication difficult and I don't know anyone who plays from that angle for reason X."

Any suggestions or help? Am I just being obstinate?

Thanks for any and all help.
