I am a busy guy. But I'm not in a rush so that's fine for me.
Since the V5 map update it is much easier to get specific Pokémon as Sphex mentioned and I have much renewed energy in collecting Pokémon.
I do wish we still had access to old school style maps though. Mainly because the encounter rate was much higher, but for nostalgic reasons too.
Ohh and it was cool to see what other people were catching there too.
Overall though I think the new maps are an amazing improvement in all other ways.
