1) The update makes Pokemon about 80% harder to catch
2) Pokemon escape about 95% more often (especially rare ones)
3) instead of fixing the three foot tracking system glitch they decided to take it out completely grass doesnt help
4) THAT MEANS NO TRACKING POKEMON ANYMORE
5) Come on that one deserves two mentions right, to add to it I noticed that leaves dont rustle in areas where Pokemon are anymore
6) these are only the things Ive noticed so far in my first hour of playing it since the update
