D&D is based on dice.

We even have a little die in the UI that we can change colors. The people who originally wrote the game understood that while a MMO could never be like PNP they at least tried to keep with the proper flavor or things.

That is worst case.... best case is a simple explanation in the tips at the very beginning of the game.
