You know, I completely overlooked this thing in previous editions because it was mostly a very cool paperweight, but it's damn near unkillable now unless your enemy has a Shadowsword or a couple of Cerberoi lined up. Can't be locked in combat because of Unstoppable, so it just kind of wanders around firing two giant large blasts a round, panicking things and chewing on tanks, I guess? Certainly funny if it just walks through a volley of Kratos meltas and hugs it to death with the big claws.

No split fire is a mild pain, but what are the terminators it can't easily eat going to do, chip two wounds off it?
