Only reason I say to get damage to SBB10 is so you don't become one of those pity cases on Reddit who fail at SS loop or leave Maxwell with a few thousand HP. Every little bit of damage is gonna help, so why gimp yourself from the start? Damage is the main reason I advised having some status removal for Maxwell (Injury). No reason to do lessened damage if you could fit status removal/immunity.

As for your Squad, You should drop Elza for a Dark duffer. Her Spark buff gives 46.6% (0.7 / 1.5) damage increase to units without spark spheres if you spark perfectly. Having a spark sphere reduces the effectiveness, of course (ex: 0.7 / 2.0 = 35% damage increase for Rowgen with Steeple Rose) . A Dark buffer gives you a flat 50% damage increase to every non dark unit. I'd move Themis down, but then you'd have to seriously rearrange your squads.

Have any other healers or Dark Buffers?

On to your spheres, putting Leomurg on Themis seems pretty questionable. Probably a better Idea to put it on Rowgen.
