I was super active in the old system. Would defend our gyms/territory and make sure to keep it our colours. Spend a massive amount of dust on epic defenders. Now I have 20-25 defenders that just sit in my poke storage doing nothing.
I drive by gyms I would normally take down but now I don't. Could care less really. Everyone and their dog has Tyranitars, Snorlax, Lapras now. Plus if I knock people out of gyms they get coins. Now they can just sit in those gyms.
Game is dying IMO.
