About:

Compare item stats against equipment sets on the Currently Equipped tooltip using SetCompare. This makes it a lot easier to maintain multiple sets of gear, since WoD doesn't resolve the problem. Comparisons will be added for gear which:

• Uses the same slot(s) as the item which is being compared
• Belongs to a equipment set
• Item is in your bags
• Comparison is not already displayed with the default Blizzard tooltip somehow (currently equipped, comparison item is part of a set already, etc.)
