Aurora only sucks as much as the people using it. Put it another way, lets take that 60k number i mentioned before, that means aurora is essentially "mitigating" 60k worth of damage provided your healers arnt overhealing you like idiots. In order for a rampart to mitigate 60k worth of damage on a 200k hp tank you would need to take 1.5* your healthbar in damage while the 20% mitigation from rampart is up. Outside of some nasty split busters which you arnt invulning for some reason you arnt going to take that much damage. Provided you have a remotely competent healer, its nothing to sniff at, let alone suggest removing like the person i responded to suggested.
