Niantic please add this

I love this game but there is something I would like them to add. I want them to add a feature were like the raid if you see a wild pokemon you have an OPTION (optional) to can fight it to make it easier to catch the pokemon and then all you have to do is heal it but the cp and hp stays the same. Also if niantic is not going to can you add mega evolutions also can you add were if you see a wild pokemon you can kill it for stardust and xp
