I would stick with 2 dice (or maybe 2@3). This pick best is just ridiculous. Seriously, the more and more errata (and “FAQ” - lol) they add, the worse the game becomes.
Welcome Cobblepot! AA50 is a great game. If you run into problems finding opponents and/or time to play,
then check out AA50 Modules for Battlemap, and try PBF (Play by Forum) here on this website.
