I am currently using a normal Lightning Rod, and working on Heroic progression (We're 3/8 with Morchok, Ultrax and Yor'sahj down). I do however have Rathrak, but no normal off hand. So my question is the Lightening Rod the best option (as I believe it is) or is Rathrak bearing in mind that I will only have a LFR offhand? As soon as I can get the heroic Ledger of Heroic rituals I know which way I'm going, but at the moment which is the best option?
