Hello yall. I was wondering if there is anyone with advice in regards to getting into my first raid. I have never raided. I have now a 70 warlock on thunderstrike eu that i leveled from scratch. Have done multiple heroics and I am close to my pre-raid BiS. But im not sure how i get into a group to do karazhan with. I have done the attunement. Do i just stay in the LFG tool? I have no guild either.. and i dont really have time to raid at set times every week. Do pugs trough the tool work? Also how is looting then? So many questions but I dont really find the right ansvers trough google i feel.
