20-30g!? Are you nuts!! Even with 10 people in your raid, that hide is worth way more than 200-300g! It is the one thing that holds most people back from getting their epic armor piece from the quest. The reason why the Finkles Skinning Knife drops in there is to give the group a chance to get the Hide.
This is an extremely rare drop. I've done UBRS at least 50x and have not seen it once. Out of all the people I've been with, probably at least 200 of those 500 people have had the quest.
If the skinner who skins the Beast and gets the hide has the quest then he can roll on the hide, too. It's not "well, I skinned it, I should get it." You can opt not to skin it, but you are taking a chance at them kicking you from their group.
It's not being selfish or anything to bring a skinner into the group to skin the hide to pass it off as loot. Unfortunately, that's the way the quest works.
You can't just deprive people of the quest just because you are a selfish numbskull and think it's your right to keep it all to yourself.
Yes, unless specified to the raid, keep it all to yourself...but don't deprive the other quest goers a chance at their epic armor.
Ay
