head to head
Warhammer 40,000: Dawn of War II asks more than Battlefield 4, and the gap is reads.

Execution · Competitive PvP
Combined-arms multiplayer shooter famous for map-altering levolution moments and 64-player conquest.

Execution · Grand Arena
Hero-driven squad RTS where wargear optimization and ability timing combine with reading aggressive opponents.
Battlefield 4 leans Execution (Competitive PvP); Warhammer 40,000: Dawn of War II leans Execution (Grand Arena).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Battlefield 4
Gunplay, vehicle mastery, and movement under fire
Warhammer 40,000: Dawn of War II
Hero ability activation and squad retreat timing are mechanically demanding
Warhammer 40,000: Dawn of War II leans clearly harder on reads.
Battlefield 4
Human teams adapt to flanks and levolution chokes
Warhammer 40,000: Dawn of War II
Opponent army composition and hero focus must be predicted
Warhammer 40,000: Dawn of War II leans a little harder on variance, though the gap is small.
Battlefield 4
Map-altering events and spawns inject noise
Warhammer 40,000: Dawn of War II
Retreat damage, wargear drops, and map control variance add uncertainty
Warhammer 40,000: Dawn of War II leans a little harder on optimization, though the gap is small.
Battlefield 4
Loadout tuning and objective rotation knowledge
Warhammer 40,000: Dawn of War II
Wargear builds and ability upgrade sequences are optimizable
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.
