Why are killer perk’s significantly worse than survivors?

Luckily, I run Agi + Lightborn + Iron Grasp on a lot of my Killers, so I don't ever need to worry about flashy saves (I usually get a lot of free hits and downs from these perks too). Plus, there's always the option to just slug everyone out. Not a fun way to play, but you can do it. There's no other way to play against Survivors dedicated to denying hooks.

FTP + BU is an unfair combo and very strong, I'd agree with that. The Killer can't bring or do anything to counter it.

Still, these are all SWF combos and need some co-ordination to pull off. If I brought these perks into a Solo Q game, I wouldn't get nearly as much value out of them.

But once you get the ball rolling with the Killer perks that I mentioned, for most Survivor teams there's no stopping it. That's the big difference in my opinion.
