How important is character class balance between the various classes? Sure, were talking OSR gaming with this question, and for many the answer will be "who cares about balance?", but for the rest of you, how important is it?
In AD&D the classes are roughly balanced by the various experience point tables (and demi-humans are balanced against humans by using level limits.)
In LotFP, classes are balance by giving each class it's own niche, with little to no overlapping.
In Adventures in the East Mark, warriors get a d10 for HD while their two sub-classes get d8s - balancing extra abilities with HP potential.
I'm sure there are other examples, but I'm barely awake ;)
So, how important are balanced character classes to you in the games that you play?
