Should I feel bad for using the koopa drone thing a ton as Bowser Jr? No one seems to know how to deal with it, and I feel cheap. All you need to do is shoot any projectile at it or grab/throw it back D:
No, you should be using it often but not in a cheap manner. It distracts opponents to run them over or get hit with a cannon ball. If they avoid getting run over, I skip across them and grab the mechakoopa. Half the time, people think the drone is done and don't expect you're going over to grab it and hurl it at them.
