I think of myself as a fairly competent HBDer, but in one of the worlds I am in, I just can't seem to get my team to win. I've built a similar team there to other teams that have had success in other worlds. As far as I can tell, the team has good pitching, the "skill" defensive positions (SS, CF, 2B, C) all have plus defenders (actually, it's one of the better defensive teams in the world), I have good, speedy baserunners and a mix of contact, power and OBP type batters. But the team only just dances around .500. I think this indicates that it is in a "challenging" world.
