The removal of the footsteps and pokevision is pretty daft... I mean it just makes the whole experience less functional, where is the + to doing that?
Thankfully I'm still grand with everything but that 70m radius is going to make one of the Gyms in my town inaccessible completely during the evenings because the gps location of it is actually just on the limit of 100m from the footpath near it. so yeah... town just lost a Gym, shame.
The radius only applies to pokemon and not gyms and pokestops. They changed the radius in which pokemon appear from 100m to 70m; while pokestops and gyms had a 40m interaction radius, which they haven't changed in this update. That's what I understood from the settings of the game they posted on reddit anyways.
Ah that isn't too bad so, just means people will be crossing roads for Pokemon but that would only happen if there was an accurate way to track them or if you have a mate walk on either side of a road to cover a larger area with their phone too.
I have to say there was nothing as cool as going around with 3 mates splitting up to cover more ground and find a Haunter who was in a shopping center where we live, really taking a mobile game to the next level.
