Only issue I see here is with the standard brave build you have up. Speaking from experience, there are (IMO, lmk if you got anything else) 2 completely different ways to build around a brave weapon, which I'll call the "Reinhardt" and the "Olwen"
"Reinhardt" builds consist of shoving as much Attack on your initiation as physically possible, meaning the best A slot is always going to be death blow, followed by either a hit and run, a breaker, or possibly wary fighter if you need the extra survivability. Speed means nothing (if you're doing it right, you should kill most units after the first two attacks), so desperation is going to be useless here, as well as Swift Sparrow/LoD (they're effectively inferior Death blows for this build).
Example: Brave Weapon+ || positioning skill || [2 charge special] || Death blow || Breaker / Wary Fighter / [flexible] || [flexible] || Atk +3
"Olwen" builds rely on quadding the opponent, which will almost always kill. However, this actually requires speed if you aren't just going to counter a particular unit type. Most units that can build this kind of build (namely Elincia, Olwen, Bridelia, etc.) tend to be super squishy, so being hit more than once from any arena-tier unit usually ends in death. Exactly what to put on depends on the unit in question (this is just a template after all )
Example: Brave Weapon+ || Ardent Sacrifice/positioning skill || [3 charge special] || Swift Sparrow/LoD/Fury || Desperation || [flexible] || Atk\Spd +3
Reminder, there are plenty of other ways to build around a brave weapon, but these are the two most common from what I've seen, with the first one being the most cost-effective to build by far.
I have a Soliel in the works right now, perfect example for a more unique brave build using heavy blade: (link to build on kagerochart for ez calculations)
From what I'm seeing here, you're using the latter example for the standard brave build. Would you mind making a seperate template for "Reinhardt" builds? It really bothers me seeing both kinds merged into one >.<
Otherwise, everything looks pretty good to me, hope you get back to work soon!
