I started to lot of Blues as I would repeatedly fail a lot and used up a ton of gems in AA..

It seems the more you fail.. the worse the saints become. It should be INVERSE of this IMO. When a person spends so much gems on saving their card, the % of yellow saints should go UP. In fact no AA should recieve anything but a yellow and at the lowest a purple. I can see the first 5 saints getting blues... but not as you go higher and higher.

Matt, you are not alone in this situation.
