I say before and i say now, this game its made for cheaters, u can't win against Fakes GPS / Bots / (put another shit here) / etc...
Old system was perfect for cheaters cause they can control gyms from their houses, and new system... the same!!
No, new mechanics are not bad. No, old mechanics are not bad. Both have positive and negative points of course, but we still stuck in same point than year ago, cheaters are killing the game more than Niantic with their slow and poor updates, at least for me.
I started playing a year ago, with server colapse, with bugs, walking km and km, with cold and heat, wind, rain, etc, and the only, repeat, THE ONLY thing that has stopped me, has been the cheaters.
