Personally I'd love to see the Steam Tank get some love... as it stands it's basically a portable bullet magnet that explodes if enemy infantry get close enough to make an ordered charge

Removing the 'destroyed on losing a round of combat' would be a start but replacing it's derisory 3 attacks would also be good. At the very least I'd like to see a return to the short range cannon from early editions (when it still caused bounce!)
Even better though would be to reflect the source material which describes a number of different configuration. 3 would be enough:
1) a heavily armed tank with a cannon.
2) a mobile gun platform = same stats but change the cannon into a Hell Blaster
3) a fast moving mechanical battering ram with no ranged weapons but attacks more in line with the horrible Skaven "Hamster Wheel of DEATH!"
Each one bought rolls randomly to see which the Emperor has loaned you
