Don't delete your low CP Pokemon yet. Maybe it will work like before, kind of... When attacking, lower the CP of your Pokemon, more morale you take from the opponent!
That is not confirmed will it work that way or not. But don't delete any of your Pokemon yet.
Not little bit about the update. HYPE HYPE HYPE so exited. Great news!!!
Only one question remains. How much will the spoofers be a problem now?
