head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Practiced Mastery
An MMO where grinding out solvable gear-enhancement systems dominates over its action combat.

Optimization · Pure Optimization
An MMORPG dominated by theorycraft, gear math, and rotation execution.
Black Desert leans Optimization (Practiced Mastery); World of Warcraft leans Optimization (Pure Optimization).
Black Desert leans a little harder on execution, though the gap is small.
Black Desert
combo-based combat needs real precision
World of Warcraft
Rotation APM and mechanics matter in raids
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Black Desert
PvP siege battles reward reading opponents
World of Warcraft
PvP arenas have light read element
Black Desert leans a little harder on variance, though the gap is small.
Black Desert
gear enhancement is heavily randomized
World of Warcraft
Loot tables and crit RNG present
World of Warcraft leans a little harder on optimization, though the gap is small.
Black Desert
grinding routes and builds are solvable
World of Warcraft
Gear, talents, and rotation are mathematically solved
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
