It does seem like many of the changes in the various editions since AD&D focused more on number crunching ... instead of the old way where 1 + 1 + 1 = 3, in the new version we are going to say (1 + 1) + 1 = 3! Then people could get into arguments over whether their 26th level fighter could dish more damage than a 22nd leve mage, etc. But the heart of the game is still there, whether you are playing 5E rules or even the old Basic Set with Keep on the Borderlands. It was still fun when all weapons did 1d6 damage. Fun and fairness do not come from the rules, they come from way the adventures are set up where the characters use their skills.
