So I have been doing scavangeing purple missions on Blizz who has a + to scavanging and his loyalty is capped at 10k and I have the first tier of the crafting legacy but I have not once gotten a purple mat from one of these missions. I thoguht you always got the higher quantity of basic mats plus a much higher % to get the rare mats. Ive done about 5-6 of these missions and not gotten any purples. Am I just misunderstanding how these work or am just unlucky?

Gathering missions like Archeology, Scavenging and Bionalysis don't have purple mats (exception would be Slicing). Those missions only have a higher reward by default, even higher when they crit.

ahh okay. I thoguht I was getting gyped! I would probaly in that case just be better off sending my minions out to do my bidding without wasting my credits at 10-14k a pop on the GTN for the mission. I average about 20 of each mat but I could just send out 4 companions for 8k and get approximatley the same ammount of mats in less time.
