It is a very great game but I wish their wasnt a cap for how much your Pokémon can make at a gym. Lets say you have defended a gym for 3 days and have other Pokémon in other gyms holding that down but the cap only lets you make 50 that first day so in that case you wont make anything for holding down the the other 2 days or from your other Pokémon, this is very displeasing.
And would it kill you to add a friends list, plus a messaging system.
