One thing we talked about in guild was your main spec being what you come as that night. If say yetok comes as boomkin cause we have healers that are not dps geared wouldn't it be fair for him to be able to roll on dps gear?  

This whole dual spec thing is gonna be kinda confusing for loot. I mean what's my main spec?  I have healed/dps/tanked all about equal since lich king. 

I think the main thing is that people have fun and want to come back. One person taking a ton of loot that other people need won't be fun. I'm just trying to figure out a simple and fair system to ensure that.  

I think sahrang is close with this idea though.
