Is it worth lvling up Espeon with ZH / FS?

Ya

I really don't think so. Sure the candies are easy, but that's a lot of dust for a "wth am I gonna use it for mon"

I used the name trick today and was lucky enough to get this guy, I spent almost all my stardust, and still have no idea what I'm going to do with him, stick in gyms I guess?

Don't do it, I still regret spending all the dust on this fella since I'm always low.
