I would love getting a 10 for one of my submissions, but I just figured out that my animations don't deserve it. Even better, not one animation on NG deserves a 10.
A 10 is mostly given to an animation which is 'fantastic, incredible and awesome'. But a 10 is also the highest note you can get, meaning when you get it, your animation is 'perfect'. But it isn't. The Castle series are amazing, but not perfect. Waterlollies contains unbelievably good graphics, but it isn't perfect. Why? Because there are always points to improve . Have you never thought after you uploaded your Flash 'argh, damn, I should have thought of that!'? It will probably be something small, otherwise you wouldn't get 10's anymore.
I have given alot of 10's, and they are all not deserved. Saying that, you shouldn't expect 10's from me anymore.
If I could get the 10's out of the system, I wouldn't do that. I still won't be giving them, but the 10's are necessary for your average score to get higher, otherwise every front page animation would have an average score of 9.0...
