How about frequent villain attacks? I really want to fight more villains
I agree that you don't need donuts to stay on top, just put in the time. I have it on my phone so all I do is check it every now and again to train and work. It's only been 11 days and I'm level 55 nearing the top 300 (Also at Silver 3). You don't need to wait, just work/train then come back later.
How often do you see villains? I mean - are they not regularly appearing on AP1 as they should?
