Most Player and Upgrade SBCs are moving away from "build a squad hitting a rating" — toward something that looks a lot more like the FUT Gallery's own scoring system.
Two formats will coexist — EA says Streamlined becomes the majority of Player/Upgrade SBCs, but Traditional isn't going away.
Our sbc_challenges parser and requirement-checker were built entirely around the Traditional squad-building shape (positions, chemistry, formation). If the "no positions, no chemistry" leak holds up, Streamlined SBCs are structurally simpler to support than Traditional ones — sum of item scores against a target, no formation/chemistry logic needed at all.
Streamlined format basics from EA's FUT Deep Dive pitch notes. Scoring mechanics and the "no positions/chemistry" detail from a community leak (@FutSheriff) — not an official confirmation yet. Full dated feed: FC 27 Leak Tracker.
