Let's Get Real - the DM's responsibility is balance

[stoutstien]

Could you give an example to elaborate / clarify your desire?

Let's say you are running any published campaign that has an encounter on page 36. The stats for the NPCs needed are probably on pg 99, their motivations are probably hiding on pg 50 and if there is any specific mechanical things involved they don't give a quick reference or even a page to refer to if needed. I.e spells.
For some things the rules are sprinkled throughout 2-3 different books so for newer people looking to DM it's a huge investment to even begin with let alone fine a way to reference them without grinding the game to a halt.
