Catan is played widely enough that many groups tend to introduce their own house rules[1]. E.g. one of my rules is: rolling 2 is the same as rolling 12, so these hexes are slightly less undesirable.

I guess if this really matters, you could come up with some set-up rules to swap some 3s with 11s, 4s with 10s, etc, so that biases towards 1-2-3 are less impactful. But that would be painstaking and annoying. I absolutely wouldn't care to do that, unless we track ELO and have an evenly matched group, which is a bit absurd in a casual game. And as in any strategy game FFA, everyone will still gang up against the current leader (even with imperfect information).
