UPDATE: Most groups use the automatic Disenchant option available in the loot roll box as of Patch 3.3.
This week, we're going to help you understand a practice that varies wildly from group to group, server to server and even expansion to expansion. "In the past few months, I've run into a situation with people who are (or who I think are) new players who happen to be 80," reader Sarabande writes to WoW Rookie. "To them, the idea of DEing BoP items for shards is completely alien (and to at least one, he just rolled greed on everything 'just to see if he could get it')."
Should your group roll for unwanted or unneeded drops when an enchanter is on hand to disenchant them? What's accepted in one situation might be scorned in another. Because there's no single way to handle the situation, it's important for new players to be aware of the options. It's also important to understand the reasons why players feel so strongly one way or another about this issue. Because there's no single "correct" method, the savvy player respects the group consensus.
