User blog comment:KaiserLos24/People Complaining About Champion VU's/@comment-1330314-20140521151442

I definitely agree that whining about an excellent VU and calling the whole thing bad based on a minor gripe is a fairly immature thing to do. Giving feedback in general, however, is not. I love Karth's VU, but I do think having everything made of pure green is a little visually confusing, and could do with a slightly different palette do distinguish his abilities from each other. Judging by the complaints, it's a fairly significant issue, which means that the collective feedback will allow Riot to adjust the visuals accordingly, something they would otherwise not have considered if nobody had complained in the first place.

In general, even the whining can be useful in improving the quality of a VU or a skin. That's how Night Hunter got his awesome hood toggle. It's better to give some kind of feedback rather than remain silent and end up with a feature that's not quite as good as it could be.
