Even with four players, especially if those players are high level, you're looking at about an hour for a small tournament and over three hours for a larger one. Expert teams will certainly be able to bring that time down, but when you're facing a dozen Crimson Lance soldiers all more powerful than you, that's gonna take a couple minutes. Now multiply that by 100 and you get the idea. Adding to the time factor is the fact that once you're in the Underdome, there's no saving and no quitting lest you want to start all over again. Best hope your host playing on a rock solid connection as if the host leaves or is disconnected, the whole party leaves and your efforts are for nothing.

That's not to say that it's all bad in the Underdome. The three arenas are all well designed, providing a nice mix of open spaces, tight corridors, easily defendable positions and "oh crap" choke points. Being able to store weapons in the new Bank is also nice and with the ability to purchase extra storage slots you'll run out of good weapons before you run out of places to stick them. Still though, the sheer time sink involved to best every bit of the Underdome isn't balanced out by the rewards for doing so. Players looking for a challenge will certainly get one but a feeling of accomplishment is the only thing you'll get for meeting that challenge.
