head to head
Neither is simply harder - they are hard in different places. BlazBlue: Cross Tag Battle demands more reads; Warcraft III: Reign of Chaos demands more variance.

Reads · Grand Arena
A tag-team anime fighter where team composition synergy and tag-in reads define competitive matches.

Optimization · Grand Arena
Blizzard's hero-centric RTS where build-order theory meets surgical unit micro against humans.
BlazBlue: Cross Tag Battle leans Reads (Grand Arena); Warcraft III: Reign of Chaos leans Optimization (Grand Arena).
BlazBlue: Cross Tag Battle leans a little harder on execution, though the gap is small.
BlazBlue: Cross Tag Battle
Cross Combo and tag setups require practiced execution
Warcraft III: Reign of Chaos
Micro of heroes and units decides fights
BlazBlue: Cross Tag Battle leans clearly harder on reads.
BlazBlue: Cross Tag Battle
Tag-in timing and team-based opponent modelling add adaptive layers
Warcraft III: Reign of Chaos
Scouting and out-guessing a human opponent's tech
Warcraft III: Reign of Chaos leans clearly harder on variance.
BlazBlue: Cross Tag Battle
No RNG; all mechanics are transparent
Warcraft III: Reign of Chaos
Creep routes and item drops add randomness
Warcraft III: Reign of Chaos leans clearly harder on optimization.
BlazBlue: Cross Tag Battle
Team synergy optimisation and assist routes reward systematic play
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.
