Well guys, the PTR has been updated with a release candidate build, what exactly does this mean? We can expect patch 4.1 as early as next week tuesday, now this isn't official yet but it's a very educated guess.
Now, don't panic, you still have a day or two to get prepared for the patch, I'll do a short outline on what things you need to do in order to prepare for patch 4..
- If you still have obsidium/uncommon gems, get rid of them. Markets will be unstable for a least a couple days, if not a week or two.
- Go into ZA and farm whatever you need/want in there, especially if you're an enchanter, snag yourself the executioner enchant.
- Get ready for pet demand - there are new achievements coming out with patch 4.1, so pets will be in heavy demand, craft engineer, snag vendor pets and get ready to sell in unusual quantities for at least a week or so. Also, if you have time, park alts at nest locations for free/easy gold.
- Stock Volatiles If possible - stay away from volatile life though, as they'll most likely crash due to botters going over to herbs.
- Get ready for gem demand - new gear from heroics = people need gems, static stats will sell best.
- Get ready for enchanting scrolls demand, again, new gear from heroics will increase the demand for enchanting scrolls. Check the loot tables for ZA/ZG to find which enchants to craft.
- Craft any other type of craftables that will be in demand due to new gear from ZA/ZG, namely belt buckles, spellthreads, leg armors and such. Have a good/hefty stockpile for at least the first we days/week.
- Save up honor/justice points and turn in ASAP for Maelstorm Crystals and sell for normal prices I.E. before they crash to oblivion.
- Park alts at locations of Cataclysm Zone Rare Elites and camp their spawn/check every so often. Their loot tables got updated, and can now drop epics & even a BOE mounts.
That's a pretty hefty list if you ask me, so why don't you get to it and start to prepare for patch 4.1? You've got roughly 48 hours before the patch hits ( hopefully ) so what are you waiting for?
