The solsphere-boosted soldier skills should do way more damage baseline. Since it's a difficult condition to meet, it should reward you with skills that have scaling at least on par with real promoted class skills.

I'm talking either 140% swa (increase the final damage by about 30%) or + 100% light atk (either as a separate, armor ignoring hit, or added into the base damage)

Notably, this isn't far from how Enhanced Solsphere Retreating Swipe, Roundtrip, and Turnover already functioned with the Enhanced Solsphere at 100% Light ATK and no downscaling per-hit, as well as Bash if you wanted to spend 1m on it instead of a spell (a meaningful choice, I found!). This was actually a really, REALLY good part of Flash's gameplan and made its damage output actually functional in a game where raw SWA attacking is otherwise piss-poor. The damage functionally approached spell scaling but in a more difficult to use way, because those were your ONLY options.
Given that I can shit out better damage on an evoker round-to-round in an AoE with absolutely zero setup, less strict stat requirements, consistently better hit + evade ignore options, and virtually no positional requirements, plus tagging in better extra effects and more consistent class synergies, I don't think that particularly warranted the double hammering it got.

(Naturally, this was also an aspect that Speed could also just make plain better use of - especially with Destiny adding extra damage to the enhanced solsphere. It was a good part of why I advocated for CF to apply to the sphere back when, and now)

The rest of the soldier skills don't proc solsphere damage and do have generally mediocre numbers in comparison. The only one that feels like it compares is Execute, which is a 50fp 150% SWA AoE. If you're pumping up to 130-140 SWA that puts it on par with.. like, air pressure?
They could absolutely do with a mechanic that brings them up to snuff, even if it is just a '.. and the solsphere does damage to everybody affected.' rider.

That's the thing, the discrepancy between soldier skills that proc the sphere damage and the other ones is massive. I think they shouldn't be reliant on the solsphere to deal decent damage.

Instead let's just make it a maximum of 1 damage proc on your turn per foe per round, but in turn any solsphere-enhanced skill would deal actual damage, like a real skill or spell. So you don't need to rely on a wonky setup of dribbling a ball around a guy to do any sort of decent damage. But you could still use the sphere to do a bit extra.
