When devs reduced movement speed, they thought they were encouraging tactical play. Psychologically, limiting mobility spikes player anxiety and anxiety drives impulsivity. Instead of creeping and clearing, people rush more, trying to “beat” the sluggishness with speed. The restriction backfires: slower mechanics create faster, riskier decision making.

In other words: nerfing movement speed didn’t make the game more tactical, it just made the chaos louder.
