Confirmed: Rares from S. King

100% possible. i'm posting this as a bug because i've seen multiple people reference that it was specifically mentioned as not possible.

Witch Doctor, lv. 12
have beat SK multiple times, perhaps 5-6. +42 MF. in the 2nd or 3rd time killing SK in multiplayer (first time with 2 others instead of full party).

received 2 rares and 3 blues and other things. no screenshot, sorry.

can someone clarify if it should be possible to get rares for killing SK after the 1st time? thanks!
