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

Optimization · Practiced Mastery
An MMO where bar-swap rotations and set-build optimization carry endgame.

Optimization · Pure Optimization
A slower, more deliberate MMORPG where optimal preparation and class knowledge define performance.
The Elder Scrolls Online leans Optimization (Practiced Mastery); WoW Classic leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
The Elder Scrolls Online
Action combat with weaving and rotations
WoW Classic
Slower combat reduces twitch ceiling versus retail
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
The Elder Scrolls Online
Cyrodiil PvP adds modest reads layer
WoW Classic
World PvP and battlegrounds involve real human prediction
WoW Classic leans a little harder on variance, though the gap is small.
The Elder Scrolls Online
Loot tables and set drops
WoW Classic
Resist RNG and gear drops add meaningful hidden randomness
WoW Classic leans a little harder on optimization, though the gap is small.
The Elder Scrolls Online
Rotations, sets, and build theorycraft central
WoW Classic
Class specs, consumable lists, and dungeon routes are deeply solvable
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.
