The main thing that keeps me from enjoying optimising teams these days is the mass of options to sort through. I'd like to propose a detailed sort/filter function for characters that would allow you to search for things like:
- Stat buff: Accuracy. Target: Party. Delivery method: Any. Power requirement: 1 or less.
- Stat buff: Focus. Target: Self. Delivery method: Active Skill only.
- Stat reduction: Yang DEF. Target: Any enemy. Delivery method: Spell Card only. Power requirement: 0 or less.
- Stat buff: Spirit P increase. Amount: 0.5 or more. Target: Party. Delivery method: Any.
- Attack element: Fire. Quantity: 1 or more. Target: All enemies. Delivery method: Basic shot only. Power requirement: 2 or less.
- Attack element: Moon. Quantity: 3 or more. Target: Any. Delivery method: Any. Power requirement: Any.
Then have the friend list show only characters who meet the criteria. I understand this would probably be a lot of work; it's largely coming out of "okay, I need two more fire breaks and one accuracy level" and not having a great way to find them beyond semi-effective wiki searches.
Something similar for story cards would also be handy, but those can at least can be browsed at a glance.
