I agree, if you have to consult 50 charts and formulas to calculate damage in a single round of combat that's going to slow the game down too much. No need to go full computer rpg though, I could see a DM pulling out a laptop and writing some scripts to handle some of the math while keeping the rest of the game tabletop though.
That could ease some of the burden yeah but you still have to know the tables pretty well to be able to predict and plan what your combat is going to look like.
