Yeah they really need to spread the Pokemon out more.
I live in London, one of the biggest cities in the world, work in a really densely populated area, and yet if I go to Pokevision and turn off Pidgeys, Spearows, Ratatas, Zubats and Drowzees hardly anything else shows up.
I just came across a Wortortle, first one I'd ever seen. He was 700CP, I used a Razz Berry and hit him dead on with a Great Ball but he escaped, same thing happened three times then he ran away. So disappointed, there was nothing else I could have done.
If a Pokemon runs away is it gone for good? Like if i reset the game will it appear again (as long as it hasn't despawned)?
