well,
i've been running dire maul with my 70 warrior and priest to get some patterns & the blacksmith book.
after picking up a bop tailoring pattern up to three times on my warrior (from chest), I put master looter on, and put the off char (priest in this case) on pass to loot.
(ticketed the pattern, so priest got it in the end)
that way the warrior will get everything, and the off char(s) will get their stuff when the main sees it.
no need to switch, no need to press rolls.

and, when you are in a regular 5-man group, distributing loot is just two clicks away
