I am also trying all sorts of downright insane experiments to try to help seed the market. The market is drenched with some of the less popular lvl 50 set IO recipes and especially with the highest tier of invention salvage. I think a lot of folks could pull their high lvl common salvage off the market, vendor it, and have some spots freed up and still plenty on the market.
Where it runs short is on some of the lower tier common and uncommon (white and yellow) salvage, some rare at all tiers, and the popular categories of recipes at all levels such as Resist Damage, Gaussian, Good healing ones, things with procs, PBAoE, Targeted AoE, etc. And we haven’t even talked about purple recipes. They are honestly worth a lot of influence/infamy, but once you have inf coming out your ears, you still can’t find the ones you want on the auction even if you were willing to pay 100mil ea for them.
There are a lot of ideas floating around about how to loosen up the market to get more stuff on it. I think that there are a few things that can knock the edge off some, but that for some reason the supply and demand for certain items is such that no amount of strategies will fix it. The only real solutions I see for the recipe shortage is to increase drop rate on the ones that are in high demand or do the dreaded artificial seeding. In the meanwhile, I’ll keep playing with my insane experiements. My latest one is to level alts up to 20, 25, 30, and 35 respectively, freeze their xp, then just play them for months and months until I can get the low lvl set IO recipes I want. Hey, it keeps us busy. lol
