I'm referring specifically to the fight against Livia in her magitek armour, where you have to fire the cannons at her to do any real damage. If you hit her with the cannons, she'll change aggro to you. When that happens, run into the middle of the arena and stay there. Someone else will hit her and pull her off you soon enough.

The number of times I've been doing MSQ Roulette recently and people have continued to stand either by the cannons or the missile piles, causing either the cannons or the magitek hands to get destroyed, is too damn high.

Please. Please just go stand in the middle. I hate getting Meridianum instead of Praetorium enough as it is...
