So I've still mostly been focused on PvP for the last week or so, and almost exclusively on my warlock. He's up to 26,217 HK's, which brings my total across all ten of my toons to 61,646.
When I haven't been queueing for battlegrounds, I've mostly been spending a little bit of time focused on gold making. For me, at least so far in Cataclysm, my biggest money makers have been enchanting and jewelcrafting. I'll start my day scanning the Auction House and using TradeSkillMaster to figure out which scrolls are selling profitably. I'll then craft any that I don't already have posted, focusing primarily on those that are used on 300 level gear and better as I find those sell more dependably.
I then hop over to my Jewelcrafter and use the spreadsheet from Consortium.net to do the Ore shuffle for the day, which usually involves buying a bunch of stacks of various ore, prospecting it all, cutting rare gems, making jewelry with the uncommon or transmuting or selling some of them depending on prices. The jewelry then goes back to my warlock for disenchanting, which feeds his scroll making business.
I've also got two transmute spec'd alchemists, so every day on both of them, I'll do a quick living elements transmute. It's usually good for around 150-200g profit per day each for just a couple of minutes of work.
It's not a huge enterprise and it's never going to get me gold capped, but it keeps me at a very comfortable level of gold.
I might do a bit of PvP on the rogue as well as those seem to be wrecking things on the battlegrounds at this point.
