1)4/5-wide(please! This is so pervasive in modern pro FB)
2) Goal Line
3)3-Back or "Full" Backup field, as in those that used to be common in College Football for the triple option and what not.

I agree, there needs to be more formations, pistol formation as well.

I would also like to see trick plays/Play action and goal line formations on both sides of the ball

Historical play seems to be a big part of this game. Different eras had different trends of skill position players. Tight ends and wide receivers are used more now than they were 20 years ago when running backs were big, and full backs are becoming almost obsolete. This is showing up pretty clearly in the historical rosters too. It would just make sense that we would have these formations available so that we can best utilize whatever quality skill position players are available for are rosters at any given time. Please make this a priority for the next game.

Bump - this is a big deal to me

Goal Line is a must I say.
Weird it's not in yet.

Also, no reverses? This is a big omission. Please add to playbook
