Yes please.

+1, not sure if Spo's OP clearly stated enough (doesn't hurt to be on the safe side) but I think a "Concede" option for the Sparring Mode in place of flee that can be activated anywhere on the field (or on the edges, depending on conflicting opinions) with a 100% flee chance would make sense.

Also, to go along with it, the regular mode be given a second prompt (if it doesn't have one already) to clarify the fight isn't necessarily considered a spar, could pose actual IC/RP harm to your character, etc, etc.
