Hello, everyone

I've been trying to get some aethersand lately - specially dawnborn (we all know thats the interesting one) and the specific ones for the gathers (leafborn etc.) - Now I've got two stacks of duskborn sand - and got maybe around 40 dawnborn (aswell as leafborn etc. - heck, I even believe I got more of thoser after all!). Am I doing anything wrong? Is there any method to shift the droprate more to the dawnborn? Am I just terrible unluck? (I know the sample size is to small - but has anyone else noticed this... unbalance between those two?)
