I've seen at least one syringe or bnp per match, so

I wouldn't call it a crutch, it takes effort therefore it's not a crutch perk

He can consistently get hits through pallets, that's an EXTREMELY strong ability that people seem to overlook. And tier 3 doesn't take long at all with the right add-ons, you can get there in just a few chases.

Blood Warden and Remember Me are not at all crutches. They're perks that are only strong at the end of the match. If a killer is good enough to not make it to endgame, they're worthless. If a killer is constantly in the endgame, they probably need perks to help them out a bit.
