Yeah, so, maybe the message is that you *should be in Northrend making 150g on one character. I'm not insisting on it -- part of WoW is farming rep, gold, mats, etc., your own level or not (but it's not a lag issue or Scarlet Monastery would've been nerfed to farmers eight times already). I haven't gotten around to running Onyxia yet but have read it's good fun and probably worth doing now and then anyway.
