By FC rules, do you mean a pools-only format? I looked at it the other day and it actually seems mad hype. Say you start with 40 entrants. You do eight pools and top three advance to 2nd round pools with 24 entrants remaining, then you do four pools and top two advance to the final round of pools with 8 entrants remaining. Then you do a giant final showdown pool and the top two from there advance to a traditional Grand Finals set.
