Reynard said:Not really. Rather, good game design would allow you to decide Ragnar the Righteous grew up on a farm and knows a little something about husbandry. And then, if husbandry has no in-game benefits, not penalize you for such, or if it has in-game benefits, requiring you to spend the same resources you would on any other beneficial skill.
Which D&D does.
It's up to the DM how difficult he makes things for his PCs. If they need max ranks in any certain skill to stand a chance, then he's encouraging powergaming by making it all about the numbers. A good DM will have a reason for a PC to have a fleshed-out background, including skills.
You know what's awesome? Someone who's not a bard with the Perform skill. No, that ranger might not be Inspiring Courage, but he can provide a melody for the actual bard and effectively Aid Another if the DM allows it (which I would). Tactically superior? No. But concentrating only on what's tactically superior to the exclusion of all else is the definition of powergaming.
