Seeing through the friggin Rook
I think that nothing should impede your line of sight to your avatar, including other people's. One of the major things that gets me killed is having a rook (allied or not) impede my view of the battlefield. Having to adjust the camera, is time taken away from me, and not being able to cast shiedl, or have my access to the battlefield blocked while in a fight can be a death sentence. Not only that, but your own avatar should stand out a bit more, especially on a cluttered battlefield. Your own character can get lost in the background.
