I've been giving this a little thought recently, and I think that it would be a good move on Blizzard's part to combine parry and dodge into a single avoidance stat. Currently, tanks in particular have to balance their parry and dodge ratings to get the most out of both stats before diminishing returns. While I admit that it encourages tanks to gear, gem, and reforge intelligently, I feel that since the two stats are literally identical in functionality it would really help to streamline tank stats.
What do you think? Good idea or np?
