In Fifa 13's Ultimate Team mode, every player (card) has a preferred formation. Every squad is playing in some formation (obviously). When a player card is placed in a squad, the formation compatibility is evaluated. It may receive one of three ratings.
- Full formation compatibility, provides bonus to Chemistry. This is only awarded if formations of squad and a given player are exactly the same.
- Formations are somewhat compatible, seems to be neutral to Chemistry.
- Formations are too different, gives a Chemistry penalty.
Now, the rules that decide whether a formation of a player is at least somewhat compatible with the squad's elude me. What are they?
