Current T2 raiding groups that i'm aware of on crick:
Sons of Europe (contact lagg/hehir) SoE typically raids at times convenient for europeans.
NBA (see sig, contact me)
Asylum (contact Iriddian, Fexelea, Castielle).
Freia also seems to be doing some stuff with Carebear Consortium.
you might find with the current instance cluster burglars aren't actually that useful, and your warden might be a little under-geared for main-tanking. But intelligent, eager raiders are always difficult to come by... gear is not.
Feel free to send me a note in game, and I will probably send your burglar a lotro-mail if i can remember.
