They enjoy or get satisfaction from one part of the game without enjoying or getting satisfaction from another part. Being happy there are methods to skip or minimize the part they don't like is pretty reasonable. There's no reason in a recreational hobby to struggle through something you don't enjoy in order to do something you do.

Personally I think the battles are the best part of Pokemon but if folks like the story, the exploration/discovery/search, or the collecting parts of Pokemon but don't like the battles it doesn't hurt me if they do something to minimize them and they aren't lesser for doing so.
