Question: how many moogles, if any, do you guys keep?
Right now I have 130% so I'm thinking to just keep 100%s worth in case I pull something good and use the excess. I have another 50% of moogles in my inbox and I feel like I'm beginning to hoard moogles for units that may never come. Meanwhile I've got so many units that need farming and moogles could save me some time on those.
Keep 100% in the tank in case you randomly pull a unit who benefits heavily from their TM (Aileen, Tidus, etc.), keep 20-30% floating around in case you need to help something along on priority, use the rest judiciously on whoever is in your current TM farm team. TM% is TM% is TM%, really. Maybe keep an eye out on the next banner or two in case you think there's something really important coming up for your team but hoarding them is mostly pointless.
I say this as someone who nearly hit 300% in Moogles this month.
