There are multiple people camping Wenna and buying out her limited quanity recipes, and putting them on AH for huge markup. While this in itself didn't bother me, I decided I really didn't want to pay 4-5g for a recipe that costs 20-odd silver, so I stayed by her for 4 hours, poking her more than once a minute while I was studying, but it didn't spawn during that entire time. I had to log and do life, but I was really disappointed that I couldn't get the recipes for my own use, despite putting that amount of effort in.
Would it be possible to increase spawn times for the recipes? Would also decrease value on AH which seems more fair, considering the population on the servers (Darrowshire here).
