Has anyone else considered the character selection / % class base this may (imho will) have? And I'm not saying for any better, or any worse; I simply think (law of large numbers) that people would tend to pick 'Tanky' build vs. glass cannon bowzon for example, if trying out Hardcore first time. Maybe not everyone does this, but I would argue the initial class selection effects are somewhat (not exact math I know) but '2x or double' as the change could cause more Tank builds in Hardcore, while they last, which means more Tank builds in Softcore once they initially die. And everyone dies in Hardcore
tl;dr I think a lot more defensive tank builds will be seen in both HC and SC. My two cents!
