Great Idea for Looting in Dungeons

I think the best way to make sure no players ever lose out on loot they desperately need unfairly is to limit needing to items that fit the bonuses your character needs in the talent spec. he/she joins the dungeon in. For example this will prevent a Fury Warrior from being able to need on a sword with both Dodge and Parry bonuses that a Protection Warrior also needed, but lost to the Fury Warrior, who didn't need it but wanted it.
