I see both sides of this, but I agree with Gaia on this. That's exactly what I wanted to say but lacked the words. If the item is expensive, then the wolf will not likely sell for anywhere near what it cost to use the single slot besprinkler until you get what you want because of the high odds of it require a bunch of uses. Even if the original WW is a gorgeous grayscale or all natural colored with only one bad color (which is insanely rare in itself), the cost of the numerous single slot besprinklers would make it not worth reselling because of the investment as well as how much the value of wolves have tanked. An expensive item like this is only useful to the user because of the lower resale value.
If a color could be hidden, then I'd say no support, but since all 5 colors are blatantly visible with insanely low odds of getting something decent, I support this.
If a pattern came out to make specific layers much less visible, then I'll go back to not supporting this. And I mean less noticeable than maned. More like as small as something like claw tips or something.
Edit: If it's expensive for ms though, I can see it being a problem as another ms sink.
If it's available for pebbles it can be seen as too easy to get. But if it costs millions of pebbles it could be a good pebble sink and take reasonable time to save for. Idk.
