Maybe there's three plinths to go with the three pillars?I’m thinking there might be four pillars to the game.
• Character creation and leveling, choosing spells and equipment
− the optimization a player does between sessions.
The Optimization meta-game, won at chargen/level-up
The Background of the character, and it's ongoing personality growth & development
The Relationship between the DM and player, and how it can be leveraged.
...not entirely serious...
