Possibly small but nonetheless a loss, and adds up faster than you think; especially when you have SS as a gap closer at your disposal.
Typically you don't need BoS unless you're doing something very unorthodox during a fight, bar Thok this tier perhaps. Additionally SS is so valuable as an escape, gap closer, mechanic gimper and general clutch-play-maker, there isn't really any negatives to consider other than a CD. But ask yourself: Do i move so much every ~20seconds that SS in unusable? I'd say if the answer to that is yes, you are either doing something wrong or someone else should be doing that job instead of a melee like yourself.
Then you bring in the exceptions, usually for mechanics which make BoS particularly considerable. Malkorok for example, it is very far from mandatory, but could help you if you struggle with movement and positioning. Like i mentioned before, unorthodox strats usually depend on something like BoS (Iron star kiting, Malkorok ball soaker etc.) and this is where it is strong.
Same goes for last tier really. If you are really pushing in PvE there isn't reason to not use SS most of the time, more notably so since the implementation of friendly target stepping. SS is extremely strong, no questions to ask.
