hope this wasn't previously mentioned, i'm new but nothing came up on any searches so here ya go
Well this worked best in SM, alliance always strolls through there with a 60 and i was only 38 at the time, but there's hope!
mind control one of the elites that use abilities (like a mage) and nuke the crap out of their lowbie, you won't get flagged for pvp and neither will the mob, they have to either run like hell or take it.
warning: if you use the ATTACK ability or right click them with the pet, you will both get flagged for pvp, but if u use abilities like frostbolt, etc. noone gets flagged and they get ownt.
edit: it's also great for RFD
