I am not from Immo, but I am a GM in a guild in EU Stormscale.
For these circumstances we usually give the item to the player for the minimun bid value ( 20 DKP = 2 bosses worth ) since it is clear an upgrade for him and he is getting it im min DKP.
Usually by the time you get to Golemagg anyway, and start farming for SOD, the 20 DKP ( in our case but you get the sentiment ) will not make the difference in the overall bid, on a item that usually goes for 300+
Also we have Mages/Locks Priority on SOD, and Droods go for Finkles usually.
