Yup. It's seemed very out of balance recently.
I'm for more balance!

I really like the idea of making the Ice King RE seasonal.

I don't see the point in changing this. if you don't battle, ignore it, if you do battle, you appreciate having another opponent you sometimes get to fight.

I'm with . Either make him seasonal, with a spring/summer battle opponent as the opposite.

That, or make it so you only find his REs in Arctic Frost. I always found it weird that I get challenges when I'm in Darkside.

I don't like this Suggestion or the seasonal variation of it. I've got nine more pets to fight this guy to ten wins, limiting it to just half a year would take me forever!
