Character Building and the Three Pillars

Following on from my previous post, one other big change I would make to character creation in D&D (that they definitely won't be making, worse luck) would be to have the character's class determine how they interface with the Combat pillar of the game and everything else about the character (ancestry, feats, proficiencies, even sub-class) determine how the character interface with the Exploration and Social pillars.

The key consequences here are that every character will be useful in combat (which is, frankly, the core experience of D&D) and every character will also be useful outside of combat. Furthermore, this means that you don't ever have to choose between eking out every possible combat bonus or being useful in the social or exploration arenas.

But, as I said, that's definitely not the way they'll be going. Having cleverly identified the three pillars of the game (albeit not actually knowing what one of those is), they've made sure to focus just about everything on one of them.
