So, based on the abysmal drop rates, it seems most players around here agree that spending Manda on Elite Requests is a waste. I've seen lots of people suggest using your Manda to instead refresh your Expeditions, mostly to get Metrons. My question (for those who've been around for a while), is that truly the most efficient use of them at this time? I've been tempted to drop 50 on one guaranteed Metron in the shop, as opposed to 30 on the chance in the Abyss, but if the drop rates in there aren't that bad, I'll hold off. Thoughts?
