One of my issues with the squad-builder is that when you get to the table you can't easily tell if your opponent's list is legal just from looking at his cards. Not just for the very rare folks who deliberately cheat but folks make mistakes. And it seems there are going to be different formats where upgrades are different or have special requirements. Shouldn't the app have some way to share lists quickly?
Shouldn't there also be some sort of "run a tourney" aspect to this where a TO could get all the lists in the tourney? If part of the point of going the app route is to make errata easier shouldn't FFG be making it easier to collect the lists people are using and what they do in tourneys?
Players could also keep track of what lists their lists beat or lose too maybe with an option for notes on the match.
