Large siege tower has 3 sets of wheels.
The front 2 sets can move the thing forward.
The rear two turn it.
It would be awesome if instead of having 2 sets of wheels disengaging the break and moving it forward if the middle set of wheels actually made it roll back.
It would allow the siege team a lot more flexibility and also make the Large Siege tower less of a daunting. At the moment they bug out quiet a lot and often well meaning people will run up and drive the thing forward in an effort to stop it resulting in it getting far too close to the walls.

It would also be great if the roof got pulled off the model, that way you wouldn't freak out about getting the thing anywhere near a wall. At the moment it's basically just a mobile firing range because once it get's into position at a wall some one just walks up, throws a siege ladder gets on the roof and smashes it to oblivion.

The HP boost was awesome
