It'd like to see this build into the private company houses that are meant to be in development.

It would be cool to go to an instanced area of our private companies, to a training area with a dummy stood in the middle, a party could then practice tanking and strategys against it.

If the dummy was a robot that had to be crafted by carpenter/blacksmiths/goldsmiths/armourers as part of the group crafting, you could also have several types, that would act like their corresponding monsters. Obviously you couldn't really do every monster in the game, but a small, medium and large sized monster, that hits for 0 damage but reacts to things properly, and displays aggro etc.

I'd find this very useful for practicing skills where positioning of team mates is required and timing is necessary.
