I never PK'd, so it never affected me in that respect, but since I skill so much, the effects have been dramatic:
-F2P Yews are COMPLETELY EMPTY. Before the changes, I could never cut yews because each tree had about 8-9 bots attached to it. (Epic Win!)
-The mining guild is about half as full as it was before 'cause all mining bots have gone kaput (Epic Win again!)
-When venturing into the wildy, I found Revenants to be much better than PKers to run into because they a.) Don't call you "Noob" and take your stuff, and b.) are a lot easier to run away from.
I'm a much happier person now, in short.
