About restoring the 5-level rarity system for perks
Items, add-ons and offerings are divided into five levels of rarity: brown (Common), yellow (Uncommon), green (Rare), violet (Very Rare) and pink (Ultra Rare).
This system guarantees that better resources are more difficult to find in the Bloodweb and have a higher price (3000, 4000, 5000, 6000 and 7000 BPs, respectively), which is reasonable and balanced (you cannot treat the Ebany Memento Mori or the Skeleton Key like a Faint Reagent or a Toolbox, because their effects in game are greatly different, of course).
That system used to be applied to the perks, too. Then, to fix a bug in the patch 1.4.1, which prevented rarer perks to appear in the Bloodweb until the player had not bought all more common perks, they reworked the rarity system with the patch 1.5.0, removing Common and Ultra Rare levels.

We all know that:
A) the perks are the main and more fundamental mechanics of the game;
B.) every perk has 3 tiers;
C) to use a 3-level rarity system with 3-tier perks means alternatively to associate every tier with a different level of rarity or to use twice the same level of rarity for two different tiers;
D) both the first and the second solutions in C) produce unreasonable results: the first forces to flatter all the perks, despite of their different relevance and strength, the second makes equally rare two tiers of the same perk;
E) the Community is attached to the old and better system, in fact in the Wiki of every language the old 5-level classifications and colors are preserved.

I humbly ask the Developers (@not_Queen @Patricia @Peanits and other people I don't know if and which account they have) to restore the 5-level rarity system for all perks, and everybody to join this petition, provided that:
1) a bug in the perks' draw system of the Bloodweb should not be fixed by destroying two levels of rarity, but changing the algorithm: our beloved Developers, a long time ago, devised a hasty remedy for the urgent need to immediately remove a fault that afflicted the availability of perks in the Bloodweb, but now the algorithm works beautifully (the Winter Solstice event is an evidence they are able to change the resources' rarities without any issue) and the Common and Ultra Rare perks can finally be restored;

2) the perks need, more than items, add-ons and offerings, to be
divided into five groups, because they often make the difference between
victory and defeat and cannot be well treated with a 3-level rarity
system, for the reasons explained above (the most precious and powerful
perks deserve to be harder to find and more expensive to buy, but don't worry: the Developers have declared that the grind will soon be reduced);
3) with the 5-level rarity system restored, characters' unique perks
would be better ordered: respectively, Common/Uncommon/Rare (teachable at 30th level),
Uncommon/Rare/Very Rare (teachable at 35th level), Rare/Very Rare/Ultra
Rare (teachable at 40th level);
4) with the current 3-level rarity system, people cannot read
properly what kind of hex penalty is active (for example, they don't
know if it's Ruin 2 or Ruin 3);
5) it is right and proper that players, especially novices, have an
immediate visual perception of the different impact that the various
perks have on the game (for example, thanks to the 5-level rarity
system, a player who has just purchased Dead by Daylight, and that is
scared to face the killer in the chases because they do not feel up to
it, knows that Spine Chill is on average stronger than Urban Evasion,
which in turn is preferable to Slippery Meat; likewise, a beginner killer
realizes at a glance that A Nurse's Calling helps them more than
Brutal Strength, which in turn is stronger than Iron Grasp);
6) the maintenance of a 3-level rarity system for perks, while all
the other resources are classified with the 5-level rarity system, is a
bleeding wound to the conceptual coherence of the game design;
7) the 5-level rarity system is one of the Dead by Daylight's
cornerstones and more beautiful than the 3-level rarity system (yeah,
give me back both brown and pink icons in the HUD, great Developers!).

Sorry for the necro, but I can't let this go unanswered.
You are derping (no offence). There were Common Perks in the game:
I still say no.
oh, what a pity
8k... Oof
I really hope that my dream will soon be fulfilled. Moreover, on the PC, players customize their icons at will: what harm would there be in giving some color and variety back to everyone? :)
I can't agree moooooooore!
