WHY can't we use the old perk designs?

By the time I purchased and started playing Dead by Daylight, the old perk icons were long gone, replaced with a cleaner looking version with borders far less bold. When I watch old videos of this game, I find that the old perks are just a lot nicer to look at. I've spent the last 5 hours or so trying to find the actual background in the game files, but they just don't seem to be present, or are buried very very deep. They added the ability to rotate characters in lobbies, but we still can't switch between new and old perk designs. You can say "but you can just customize them" but it's not the same as actually going through the rarities ingame.
