Perk Balance
Right now, killers have 4 mediocre perks against 16 survivors' crutches. They have much better perks, and have them 16 in total.
This is unfair, because it is 4vs1, and that one person has worst perks, than the other 4.
To solve this problem you should add more perkslots for killers, or remove perkslots from survivors (first option is less frustrating for survivors, so it is better).
OR
Buff killers' perks, so they would be 4 times better than survivors', not worst, as it is right now.
Comments
OR instead of making all your decisions based on killer benefit, simply buff the perks themselves that are weak, ON BOTH SIDES, and maybe fix the core gameplay issues.
So all killers' perks and some of survivors? Deal. But remember, that killers' perks need to be 4 times better than survivors'.
Most already do. Example, predator does 3 seconds, so does lightweight, but predater effects everyone. There are a few killer perks that aren’t in the 4x loop, but most are. They need to be buffed, not because they don’t 4x, but the perk itself is just bad.
