Diablo IIIThe First Descendant
Axis by axis
Execution4 vs 6
The First Descendant leans harder on execution: Colossus boss fights and intercept missions require dodge timing and aim
Reads1 vs 1
Even - both lean on reads about the same.
Variance5 vs 6
The First Descendant leans harder on variance: Module drop RNG and Descendant unlock rates drive the grind
Optimization9 vs 8
Diablo III leans harder on optimization: Set bonuses and paragon levelling are almost entirely solvable
