Breakfast Topic: How do you distribute 5-man loot?

I've noticed something a bit unexpected and confusing over the last few months: apparently, the way my server generally deals with loot in 5-mans is strange. Rather than rely on the in-game roller, we pass on all loot, and let people call need on a piece. Then we all roll need or greed on the stuff. If there's an enchanter in group, they can disenchant the loot for the winner on a greed roll and hand over a shard. Lately, though, since Blizzard started allowing server transfers, it seems a lot of the new 70s have come in and told us that this method is a bit weird. Why don't we just use the in-game rolling system? Why should enchanters be expected to automatically be willing to shard gear for non-enchanters without compensation? These are questions that are really alien to most of our server community, but there they are.

So, I thought I'd ask you, dear readers. How do you deal with 5-man loot on your servers or groups? Do you just use the built in roll system? Do you use Master loot? Do you pass and discuss? Is it generally expected that an Enchanter will gladly shard loot for everyone in the group, or is it expected that an Enchanter only need shard his own loot?
