I don't if I'm just being slow, but I've only very recently realised that there is a fairly serious bias towards both Combat skills and Melee trait dice in the published heroes. I had been musing over the fact that we generally seemed to get more than 4 Combat skills total when drawing random parties of heroes, and I finally decided to check. Numbers below. I haven't included the promo heroes, as I don't own any of them and can't be bothered trawling through the BGG image galleries for the stats:
Skills (total skills across all heroes):
JitD: 22 Combat 19 Subterfuge 19 Wizardry
WoD: 8 Combat 7 Subterfuge 3 Wizardry
AoD: 7 Combat 5 Subterfuge 6 Wizardry
ToI: 10 Combat 4 Subterfuge 4 Wizardry
Total: 47 Combat 35 Subterfuge 32 Wizardry
Trait Dice (total across all heroes):
JitD: 20 Melee 18 Ranged 22 Magic
WoD: 8 Melee 5 Ranged 5 Magic
AoD: 7 Melee 6 Ranged 5 Magic
ToI: 12 Melee 3 Ranged 4 Magic
Total: 47 Melee 32 Ranged 36 Magic
Is this news to anyone else? Tomb of Ice is a particularly egregious offender with an enormous melee bias: there are more combat skills among its heroes than Subterfuge and Wizardry combined, and the same is true of trait dice. The original game wasn't particularly biased, and Altar of Despair is also quite close, but even here there is a certain melee-favour.
I find this somewhat irritating- it means you'll see each Combat skill about 50% more often than a Wizardry skill.
Interestingly, in JitD the trait dice bias was actually most favourable to Magic attacks, which mirrored (though not on the same scale) the enormous bias towards magic weapons in the treasure decks.
I wonder if it's intentional- I suspect not.
