I really hope hacking/mods don't become a bigger thing in PoGo now that PvP is introduced just like it is in the main series meta. People will design 'mons with perfect IVs for battle and then wipe the floor with average players. It's why I never got into competitive playing. Then again, because people will mainly be just battling with their friends we won't run into many cheaters. I'll give PvP a try and see, but I've always been more of a collector than a battler on PoGo anyway.
