Certain skin prices...

A little while ago I bought Kog 'Maw's Deep Terror skin since I thought it would look cool. It's 975 and in no way should it be that price after playing a few games with it. I know not every skin is gonna have amazing particle effects/new voice clips/ different colors just because you paid a little extra money but this skin honestly has none of that. Urgot's crab skin has more visual effects and its 520 RP. I went to support to ask for a refund but I had already used up all 3 of mine when I was a beginner. I'm not asking for a refund but could you please make this skin worth the 10$? I had no way of knowing what it would give me since the site just shows splash art maybe you should add a model viewer and ingame spotlights? But seeing the usual trend of 975 skins usually have cool new stuff this probably makes his particles blue like water instead of vomit but no it just changes his model a bit. Sorry if I sounded rude but I was given a pretty copy paste support ticket when I asked for help. Could anyone tell me why this skin is like this or could a rioter please respond? Thank you. Sorry for this wall of text btw this is my first Board discussion.
