Well, I think that if the tank is just letting the mob run around and kill people, the problem is that they're just not doing a very good job...

The fact of the matter is it's far far easier as a gladiator for me to spam buffs to get agro than it is to use provoke/taunt. if I line up 5 or 6 low cooldown buffs (30 seconds or so) and just cycle through them, I can easily keep every monster on me with no real effort on my part. I can't believe that's working as intended.
