Fastest way to farm light for anima?

[Bacent]

usually takes about 5-8 minutes from start to finish with competent DPS.

I've been in groups with multiple healers/tanks and we almost always did it under 5 minutes, unless a wipe from too much DPS on the boss and the second having more than 11%. One minute for faust, and a couple on the twinbosses

Maybe less time if people actually bothered to turn off 'previously viewed cutscenes'
