The 50 coin per day limit is ridiculous. It is also extremely lame that you can not collect coins until a pokemon comes out of a gym. Since you often lose gyms 2, 3 or 4 at a time, it means that you often get nothing for controlling gyms, because one pokemon maxes out the 50 coin limit. The gym changes also punish dedicated players for having high level pokemon. It is dumb that 3000 cp plus pokemon lose motivation faster. Once people see how messed up these changes are, you will see a lot of people moving on to different games. -- one addition --- If you like to play solo a lot, then you will have a hard time getting high end pokemon. The RAID system punishes anyone that doesnt play with groups of 10 or more, or live in high populated areas.
