Overall a good guide.
Some points that I think can be a bit misleading
1. Saying "At least 2 players on each side (DR,DMR,MR,AMR on the right and same on the left)" could lead ppl into using an illegal formation with 3 players on a side. Perhaps change it to "Use 1 or 2 players on each side".
2.There is a mix up with the arrows. Red arrows send players a role forward and blue send them a role down. Not the other way around.
3. The only gifts that you can send to/receive from friends are treatments, morale boosters, rest packs and skill points. The only in-game way to acquire tokens is via the TV rights.
