Was watching the Pokemon Go comic con panel's Q&A when the whole crowd started chanting "3 step bug". The dude laughed at them and went on to talk about something else. I guess Pokemon Go just isn't worth your time or money anymore.
Even before the bug, going hunting and trying to pinpoint the location of a mon at a time was the most inefficient way to play. Take walks through the city from point A to point B, raid the stops, hatch the eggs and catch whatever pops on your way
