Specifically, do any of you use dice rolls in your combat calculations. Basically, stuff like 1D4 or 2D6. I know there are guides/tutorials on the forums showing how to simulate dice rolls via JS. So not asking about how to implement such a feature, but rather, its pros/cons and prevalence among RM users.
I have not yet used anything like this and I do not think it could be useful as if it worked then the admin/owner of it could earn more and more and all the gambling site could be 0 by losing again and again.
