How about Cloth Physicks?

In all seriousness, we can only get as much physics as the engine allows, and being an MMO, I don't see it being all that intensive due to the fact that all of the data has to be sent from the server to the player, and having too much physics code will slow the game down for everyone. Clever animations are a good cheat for this, and that is likely what we will get for now.
