Dying Light no, not really, as it's more of a "win harder" perk. Like, if you're already winning this perk will make it exceedingly difficult for survivors to make a comeback. Usually when I use this perk, 2 ish gens are already done by the time I get my first hook; all that work for a 3% slowdown to repair and healing that will only be in effect for the last 3 or so gens and doesn't even affect the obsession. Pretty useless perk imo.
