Don't forget that the sect's challenges favor specialization rather than jack of all trades. i'd argue that the inter-sect tournament does too simply by virtue of it being a team event.
Larceny is more something we dabble in than a specialty anyway.
TBH, Lark strikes me as redundant. It doesnt really add anything new and usable to our repertoire. Basically, it works best at close range, which is were we dont want to be, requires the use of hands, which really should be occupied with playing our flute. I'm not convinced flight is such a powerful advantage in the inner sect either.
In the outer sect, you basically fight against other outer sect members and some low end spirits. Inner sect is where military service becomes common, and what are they fighting? Spirits and flying barbarians. I'm pretty skeptical that flight is some kind of unassailable advantage, frankly.
