I'm finally about to start our SoB campaign tomorrow! Very excited.
Anyway, my hero players like to be able to choose their heroes freely. Me, not so much, because I know some of them like overpowered combos. I plan to only introduce the Siren very late in the campaign as well, playing the whole thing more gamemaster-like than overlord-trying-to-win style - I want to give my players a good time, a pleasant experience and a good challenge, no more no less. I plan to draw both the avatar and the plot, to avoid unconsciously choosing anything overpowered there myself.
So what I thought I'd do for hero choice: I'd give them four stacks of heroes, maybe 5-6 heroes per stack, making 20-24 out of the 39 heroes available, counting all heroes from all expansions, but no promo ones except for Nara the Fang. Karnon and Arvel will be house ruled to get 0 and 2 starting skills respectively, to balance them. I'm also thinking about restricting the range of Runemaster Thorn's teleport, for islands.
Out of each stack, a player would be able to choose one hero. If a hero is chosen from a stack, another hero from the same stack can't be used - but the players can decide among themselves who gets which stack, and each hero player can then decide which hero he gets from his stack.
Like this, they'd have a large selection of heroes to choose from, but couldn't just take all of the best heroes and greatest comboes at once.
What do you think, is this a reasonable way to give them a good selection of heroes?
