At first I had horrible flashbacks of FF11, but this isn’t the case at all. Although you lose mettle, the lose is easily gained. I do think mettle per kill would be nice, but that’s another topic. Just saying, you get use to it. Also there’s something truly satisfying about being the last man standing and crushing a CE boss. Everyone watching while you save the day. Been there more then a few times and it’s always a great feeling.
My advice...always stay prepared for whatever might happen. Carry a couple phoenix downs to Rez players who can help save the CE.
