Perk Changes
Short and Sweet we don't need new perks for awhile because a lot perks are starting to come out and just be better versions of something else that already exist. Not to mention if something new comes out thats unique its usually trash thats not going to be used. Hex: Two can play is a prime example of that. Theres also the issue of whenever a perk gets changed or updated the default change is either aura reading or exposed.
If we drop to a release maybe 2 a year instead of 4 then inbetween those 6 month periods we could get new maps/variations. Instead of again perks that already exist thats either better or worse or the same thing different font. We could even keep the 4 a year release long as that chapter doesn't come with perks. Also if we don't get a survivor during the main release we don't need one during mid chapter. I'd much rather have more perk or power tweaks/buffs/nerfs.
We're close to 200 (slightly exaggerated there's 150) perks on survivor and I swear only at least 20 of them are actually good/decent and maybe 10 you see the same match and 132 perks on killer with again maybe 10-20 perks that are actually good.
