Now I must admit that 5 man instances are one of my favorite things in the game. Especially when you can grab a friend or 4 and laugh along the way. I admittedly have stopped doing them for the most part.
Why? Because there is no incentive to do them. I enjoy doing some of the older content given that the rewards are basically the same to me.
I think the new patch is going to get people back into the instances. The bosses will be dropping justice points instead of emblems which means that you will be able to use the rewards for level 85 gear. It is a great way to get a head start on Heroics is Cataclysm.
This likely means that I will be running them again which gives me a good excuse to finish the glory of the hero acheivements. I am not that far off currently, but just could not bring myself to do it.
Here comes Darraxus to smash some face.
