I guess it is because of the fact that signature ability regenerates and a lot of info can be gathered from them. In CS retaking without utility is extremely difficult. Also in valorant spikes take 7 secs to defuse, whereas 10 in CSGO without a kit, 5 with a kit which has to be bought (and retrieved from a dead teammate (if required), which eats time or adds to the difficulty as the body might be in a difficult to reach position).
