OP, I don't know what server you are playing on, but I doubt that the decreased activity is from the patch. Faerie has seen no less activity than before, and I dare say we are getting more folks at A's when they do pop specifically because of the patch. Hunting parties are just as prevalent as before, except now they don't bother with B ranks at all whereas before B ranks were a way to kill that 10 minutes between the last A kill and the next A spawn.
