I appear to be getting hate from some people, yet I can't understand why this is.
I don't understand it either. But to answer your question I guess they wanted it to be sorta first person watching the battle through the trainers eyes. When catching a pokemon you only see the trainers arm toss the pokeball in a first person sorta way. As for why you can't see the opposing trainer I have no idea.
