Over in the game in the game I can't wait to play, but really need a beta key for (Come on Arena.net! You know you want me!), it looks like magic damage is now based on your Friendship attribute. I'm assuming this has some sort of tie to either your guild, or friend list. Those of us that friend everyone will finally have the upper hand instead of digging through 30 pages of people every time we want to invite a specific person.
And over at the Bathesda Forums, everything has been improved with a My Little Pony tag. They don't have any beta keys for me to beg for, so I guess I'll just agree that this is really neat!
