head to head
Neither is simply harder - they are hard in different places. Tekken 7 demands more execution; Warcraft III: Reign of Chaos demands more variance.

Execution · Grand Arena
A high-execution 3D fighter where reading opponent tendencies and optimising punishment routes defines top play.

Optimization · Grand Arena
Blizzard's hero-centric RTS where build-order theory meets surgical unit micro against humans.
Tekken 7 leans Execution (Grand Arena); Warcraft III: Reign of Chaos leans Optimization (Grand Arena).
Tekken 7 leans clearly harder on execution.
Tekken 7
Long combo strings and just-frames demand high motor precision
Warcraft III: Reign of Chaos
Micro of heroes and units decides fights
Tekken 7 leans clearly harder on reads.
Tekken 7
Reading opponent's defensive tendencies and rage art timing is constant
Warcraft III: Reign of Chaos
Scouting and out-guessing a human opponent's tech
Warcraft III: Reign of Chaos leans clearly harder on variance.
Tekken 7
No RNG; all information is visible in the match
Warcraft III: Reign of Chaos
Creep routes and item drops add randomness
Warcraft III: Reign of Chaos leans a little harder on optimization, though the gap is small.
Tekken 7
Rage Art/Drive usage, wall carry routes, and frame data heavily studied
Warcraft III: Reign of Chaos
Build orders, creeping routes, and matchup theory run deep
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.
