My suggestion is to scrap Superbru entirely, never been a fan of their scoring and it's just boring overall.
Disagree. I liked Pot B, but personally I want to have Superbru pool too. Maybe not neccessarily Superbru, we can go with Kicktip like in Bundesliga pool. Though, probably prediction pool doesn't fits for knockout tournaments like Champions league, it works better on leagues.
If it would be just Pot B, I'm not sure that I would play because I'm not doing good on such kind of competition, while having Pot A leaves chances for me to win something.
