Random rigged odds, so good luck trying to catch something that you like above average, or even shiny, lackluster events under paywalls, people that will kick you out of gyms almost instantly, leaving you with close to no coins, a bragging rights simulator for funsuckers that don't have anything else to do with their life. Updates making the game lag even on good phones & support is helpful depending on the problem. Huge potential, if they even cared to begin with, much greater disappointment.
