Guild Wars leans clearly harder on execution.
Guild Wars
Interrupt timing and kiting in skirmishes
Tom Clancy's EndWar
Voice commands remove most mechanical demand by design
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Guild Wars
GvG and arena metagame against adapting humans
Tom Clancy's EndWar
Multiplayer theatre battles reward predicting enemy unit commitments
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
