Older skin prices are complete BS

So was looking at this weeks skin sale rotation and i saw demolisher nunu next top battle regalia poppy BR Poppy is 520 rp when not on sale and Demolisher nunu is 970rp

Seeing demolisher nunu right next to battle regalia poppy makes me realize just how grossly over priced that skin is. I mean it has zero VO or unique effects and the rig is exactly the same as the base skin. Demolisher nunu would be released as a chroma today. So Why is it is 970rp again? That just seems like a giant rip off to me compared to some of the much better skins you can get for cheaper price

riot should really consider repricing some of their older skins
