The consequences of impermanent death is something I stole from Mystic Chicanery.
It's an interesting concept. If you pretend that Azeroth is a real world, with real people, what is the impact of never being afraid of death? Death plays a huge role in our current society - we fear it, we revere it, we eat cake and casseroles over it. We don't do things because of it and we do things out of fear of it.
So, what would it be like if you knew all it would be is a 5 minute corpse run and a few bucks to sew a new seam in your clothes? Read his/her blog on it. It's very good and I don't feel up to repeating all of it. :)
And then there are other things as well... if you could turns things into sheep? If you could really summon demons? If you could transform into a cat? Holy shit. I could be a cat.
