@AndrlCh I had been hoarding EX cubes one of Zig's weapons and upgrades but honestly I'm not even sure if/when I'll ever even bother with them. Been making do just fine using the Millionaire/Croesus weapons fro the Collection Folders. They're not quite as powerful, but for most of what I engage in they've been sufficient. And from what I'm seeing and hearing trying to get even one of each weapon type from the top tier category (I believe right now it's the "Lightweave Klauz" series) is either entirely impossible or so grind intensive it could take months or even years and frankly I have no desire to commit to that grind whatsoever. Which means I'd have to pick just one, maybe two, weapons to make with what materials I already have and I am way too indecisive for such a narrow set of options. So I'll probably end up spending a ton of my EX Cubes on EXP Weapons or maxing out all the Techs and PAs.
