I was at PTR once. When new legendaries were introduced. Echoing Fury with socket and 90 something% crit damage dropped. It had very good DPS (can't remember,something over 1100 DPS). And low fear proc. I was furious.
Never have I seen item as good as that drop on live for me.
PTR - not even once. You have been warned.
Althought I'm really looking forward to these recipes. Even if it is another gambling game (but one useful affix at least is fixed), it gives me another source of items, beside AH. AH is fun and all but crafting my own items sounds more fun. Though I'm stillnot sure how to accept BoA items in diablo game. We will see.
