If you're looking for help completing the insane in the membrane achievement before it is removed with cataclysm's release, head on over to the JMTC forums "Insane in the Membrane Support Group."
Items to flip on the auction house for insane in the membrane achievement seekers:
- Heavy Junk Boxes
- Darkmoon Cards but mostly Decks
- List of Darkmoon Faire Items Note: Site inactive.
- Librams of Focus, Protection and Rapidity.
Since this is becoming a feat of strength you can expect a similar upward trend in the value of these items as we saw for ZG reputation bijous and coins. Don't underestimate the value of some of the lesser darkmoon faire turn ins either.
Insane in the membrane is a little different from ZG since it's harder to do for one and the items are far rarer. While ZG was being farmed for tiger mounts, polymorph pet and razzashi hatchlings, these other reputations needed for the insane title were not being farmed. Bloodsail and Booty bay rep were being farmed but the only way to increase those reputations is through questing or grinding, not through ah purchases. Therefore I expect the prices of these items to go up about 3x what they are now for those insane enough to buy them.
So far we've seen blizzard cleaning up loose ends in the old world by removing achievements and making them feats of strength. What haven't they thought of? Did they miss anything? That's the real question and anyone who figures it out before blizzard will make a pretty penny.
