All 35 allies I have were found on this site. I've noticed I get some but not many ally points from my allies. This tells me that many of us are leaving a considerable amount of ally points on the table. The reason is that you get double the ally points when you use an ally's character. The way that I do it is that every time I'm given the option to use an ally I do so without fail. I always pick the one with the highest power not because I need it but because I believe that those of us most active in this game should support each other so it's a matter of principle (I do it even on the easiest gear farming missions). I know the bronzium packs drop shards and complete characters at a low rate. However, if you double our ally points then you are essentially doubling the odds of getting something useful out of your purchased packs.
This is why I say sim tickets are a mirage. They are presented as an item that's supposed to help you when in reality they are quite literally holding you back and keeping you from getting the most out of your limited resources in the game.
I would like to hear what thoughts anyone else has about this.
