-We may add a **sub-gig** slot so one loadout mixes two gigs without full dual-main power.
+**Agreed:** each loadout has a **sub-gig** slot so one character mixes two gigs without full dual-main power. That opens a **large space of creative builds** as the gig roster grows—no need to enumerate counts; the point is **breadth of choice**.
 
 - **Reference pattern (FFXI-style):** at **main gig** level **X**, the **sub-gig** contributes abilities (and any sub-gated systems) only as if that gig were **⌊X / 2⌋**—exact floor/rounding and whether “level” means character combat rank vs. per-gig progress is **TBD**.
 - **Intent:** hybrid builds and party coverage (e.g. main damage + sub support tools) without letting a sub match a fully leveled second gig.

 - **Story:** journal or quest UI can separate **character / faction** threads from **gig** threads so players see which arc belongs to which gig.
