What features do you think would be awesome?
No matter how unrealistic it is, name whatever features in an MMO you think would be really cool to have..
For instance, one thing I thought of is as you level up, your character gets bigger and buffer every level. So instead of clicking them to see what level they are, you just look at them and see that there extremely buff so that would be an obvious sign you can't kill them if your lower level :)
Another one I thought of is it would be cool to play spy's sorta like splinter cell chaos theory except MMO, and of course more classes.
Would also be cool if you could shapeshift into various objects like cups and refridgerators, then change back right when an old lady walks by and scare the crap out of her.
