It's Poisoned 2+, AP3, Template, so Ignore cover. How could that be bad? It just feths up any Heavy infantry that's not a terminator even if it's in heavy cover (so they can still get a cover save against your plasma).
The problem is not the potential damage, it is the delivery (and the Torrent
USR makes a huge difference in that department). Whenever you get to fire the Bane wolf main gun, there is a high probability your tank dies the next turn. If you opponent has any fast
CC units you will have a really hard time to get close enough to fire the tank at all.
Vs orks I would take the hellhound for sure. Fighting xenos is where it works best! If you are looking for effective, I think 2 Wyverns will do the same job better for the same points, but personally I prefer to flame things!
