: I see everyone saying Anub can tunnel, but are we really thinking about the terrain presented here? This isn't some underground cavern; this is a Titan fortress he's digging through. Even if Anub were able to scratch through the layers of titansteel and bronze, who knows where he'd end up?
He could burrow straight down into the second level bathroom of Ulduar, where a showering Freya will scream and start slamming him with a washbrush. Anub will then, completely embarrassed, cover his head and apologize profusely, run into some furniture on the way out and make a complete ass out of himself. Tribunal wins!
: The fight's in neutral territory, friends. Besides, he's an unholy undead fiend of impossible strength. Some metal isn't really that much of a hindrance; solid rock isn't.
: After some thought, I do have to give the vote to Anub'arak, but I think a lot of people misunderstand something. Most of the votes for Anub'arak seem to be based partly on the fact that he can burrow underground to avoid the various Tribunal attacks. Well, I have to side with the commenter that pointed out that this is not Azjol'Nerub. This is not dirt or even rock. This is the (probably) TITANIUM floor of an ancient Titan fortress. Anub would need a backhoe and some good ol' goblin explosives to get through there. So. No burrowing for Anub. But still he's smart and crafty, plus with plenty of little helpers to distract the Iron Dwarves and keep them busy, as well as to soak various lasers and such. I think he'd be able to outlast and out-maneuver the Tribunal in the end.
: "... or perhaps the Tribunal has been transplanted to the Two Bosses Thunderdome..." You failed to even read the article before posting. It is assumed that the fight takes place in neutral territory, as with all TBE fights, where he would be able to burrow. >8< Spider Pride
: And I would argue that it isn't just the three faces that were transplanted. The entire room is the "Tribunal of Ages," that is, the massive computer that holds the information Brann was after. The faces are simply the defense mechanism for the computer. For there to be an event for the defense mechanism to activate (i.e., someone hacking the computer), the entire room would have to be present. The computer's "monitor" is the very floor of the room. Of course, if the floor is glass, then it'd be child's play for Anub'arak to shatter it and use his burrow.
: ... For those who say Anub cannot burrow through the Titan complex, you might be right. Except that we've seem the place being mined in the Halls of Stone itself. So obviously, it's not indestructible. Otherwise, Yogg-Saron would never have broken out, or XT wouldn't have malfunctioned, etc. Anub's strength was enough drive his spikes up through solid rock and burrow with them like a shark. Azjol'Nerub is still standing for the most part even after a war and what appears to be no upkeep, and Anub has no trouble there. And we also see bits of rubble and broken parts in the halls of stone. Maybe the main complex is tough, but I see nothing saying the halls of stone are the same.
