I don't think you can farm raids.. it's on a weekly lockout once the boss dies. But really it's such an easy fight to solo now at 90. first 2 phases are cake. last phase where you fly around Malygos.. just stack #3, your heal over time buff, up to 5 stacks.. and keep it at 5 stacks. Slow roll 1.. 1... 2.. 3 rotation. Sometimes you need to wait a sec for energy to build for 2, but just wait for it, and continue the rotation. stay out of static fields because your HoT stacks won't save you from that. Thats easy just keep flying around Malygos. You can fire if he's to your left or right, so you don't have to constantly face him. Easy! good luck
