Sorry if this has been discussed before, but I couldn't find anything like this.
I play another game as well as W101, and recently, ... a new content patch introduced the concept of "Pet Battles" -- and if this idea already exists here and I just can't find it, sorry -- but this seems to be a logical way to take Pets here.
You can duel other players' pets and pets in the wild, including rares, ... pets with no player- owner that are just hanging out in the wild.
You get five options to these turn-based pet-duel. Three attacks, which can be switched as a pet evolves, a Capture option, and a Forfeit option.
It'd be nice to see similar Pet Dueling here -- and I apologize, if it already does and some way or another, I just miss where to find it ...
