If geared enough you should be able to solo these guys. Single pulls. Banker faction so you will wreck your faction with Qeynos bank, but wont harm any other factions. If super worried about the faction there is a pretty easy quest that awards faction back with these guys as long as you do it before you go KoS. If you are a good race you start out pretty high and these guys give minor hits. I solod them on a 56 Pally fairly easily all the way to 60 (on just these guys) and was still apprehensive when I hit 60.
These guys are super easy kill and if you are able to solo them at 52 they are good till 60 and its in a city so 100 ZEM to boot.
