Unity Shuriken burst randomistaion

Hi!

Can someone tell me why, when I emit particles in bursts it always looks exactly the same way? I mean the size, the rotation, the speed, the texture sheet animation are ALWAYS the same. It is particularly annoying when creating impacts, explosions, and other things requiring a bit more randomisation other than a smoke..

I was using Unity 3.5.5 when I was frustrating over this and when a changelog appeared for Unity 4.0 I was relieved:

Now I've upgraded to Unity 4.0 and the problem still persists.. I think that it has been only fixed for general emission, because that was horribly bad too..
