Killing Corrupt Guards

[Rjones61]

When I first started on this server, I wanted to kill some corrupt human guards. Don't know why, but I guess I wanted to lay the Hammer of Justice on them. However fast forward to now, as a 34 magician, I just remembered that I once had a desire to do this. After doing some Googling, I realized I have no idea what corrupt guards are good exp/easier to kill for a level 34. So, I was hoping you guys could help. Where should I start slaughtering corrupt guards? Is it too late to profit from this?
