Fun is relative term. People are here for the DnD 5e rules not some bastardisation of it.
And if this is done for testing then its not a waste of time or resources but valuable information gathering.
Considering neither of us are actively developing the game let's not pretend to understand the development cost of features. That's why this is posted in the feedback, and suggestions section where the developers can read it, and discuss it themselves. Also if you have played pillars of eternity two they offer two different game modes, and they aren't an extremely large studio. So it's more than possible. The question is there enough community interest to make the feature worth the development cost.
