Blast mine was a fun harmless perk that already took way too long to activate. Most of the time you can't/don't get value out of it cuz the killer is far, counting on a pain res hook, etc. And when you try to trap another gen u find that 3 gens already got completed and ur random teammate refuses to keep the gen 99'd for the killer to kick. To put it another way, it is already a pain to get value out of, why did it have to be nerfed to the ground??? For what reason??
