It’s not really too unusual for a launch as big as this to have some bad units slip through QA. If it’s a handful of people, I’d even say that’s pretty impressive. This starts to effect a large enough percentage and then you’ve got something worth getting upset about.
I can see why the comparison to Genysis would exist now but I don’t think it’s a very worthwhile comparison to make in how they play out and are used in each system.
