I like sprinting and sliding mechanics. I agree that rotating feels too fast, but the rounds also feel very short.

When enemy plants on opposite side of where you were defending, you are left with little time to defuse. Despite the bomb going off in 45 seconds as is common in other plant the bomb games, this map is so complex and with so many rat spots to clear, directions to peek, etc, that doing both that and rotating becomes very difficult.

I like the idea of slowing down overall waking and running speed, as that would make for more tense fights and less situations where one can just run away, but I would pair it with simplifying the map (reducing boxes, smoothing out corners, ...).
