Glad to see this posted in the Forums. Im personally suffering from same issue. Before the recent patch I could RE lvl 49 blue enhancements 4-20 times to get a purple. Now I am currently on 176 blue Adept enhancements and have yet to attain the purple schematic.. IDK but that to me seems broken. On my server the 4 Lorridian Gemstones sell for 1.5-2k a pop. Personally i had over 700 stockpiled, but now I am completely out of resources and quite frustrated.
