What is the reasoning behind removing good things in skins?

I only began to notice this little, yet annoying detail back then when BM Jhin's recall effects and footsteps were cut from his skin. They were like the icing on the cake, everybody loved those features and I think a 1350 RP skin is perfectly worthy of them. I was really sad to see them gone. Can you at least give me context as for why you removed them the first place? Nobody even complained about them, people were actually really upset that they were removed if you remember what happened when the full version of BM Jhin's spotlight was released.

Come on, Riot. Please just give me a reason as for why you would do such a thing.

EDIT: I figured that if BM Jhin is a victim to this, then other skins might just end up the same. I'm trying to see if I'm right about this
