To get say water pokemon for me, i live in a valley and getting to a big amount of water is a drive. Also populated areas tend to have better pokemons and pokestops and people usually use lure modules on them. So overall its better.
yeah im on it atm its awesome, just dont go far from your house. Like go dirving distance, dont go like from cali to new york. If you do they will flag you for a temp ban.
