Would definitely pick it op if there was a Norde kit even with a EU proxy..
EU/Norde/International kits don't sell. I don't have the numbers on hand since I'm on mobile, but the numbers for the past 5 or so GMK sets with these kits that ran have shown a pretty steady trend of <5% order for these kits vs the base kits. Besides meaning that these kits have a statistically insignificant purchase rate, this means you need the base kit to hit the upper bounds of what even Massdrop can sell in order to be produced. This means that for small set designers not going through MD, it's not worth the time and effort to design a kit and get it mocked up/quoted by GMK. There's always so many people that will yell and complain about these kits not being included, but they seem to disappear when it comes time to commit.
Edit: I'm back with numbers now that I'm home from work.
