Basically adding a static line or text for when you enter a battle, win and lose a battle. Similar to NPC's in a way
Example of when you enter battle:
Example of when you win a battle:
Example of when you lose a battle:
The whole point of these is to get a good idea of the personality of your opponent. The more customization the better. Profanity filter can always be applied if that may be a problem or even give pre-set lines to choose from such as "good luck, have fun" or "bueno suerte" I think the community can have a lot of fun with the ability to do this, sure you can always just message you opponent but this way we get a taste of who it is you are battling without testing your modesty.
