If you don't subscribe to the Arch news feed, you're taking a chance on every upgrade, that your system will not boot correctly.
You can trivially fubar an arch install by updating your base install+user additions if you're not in the loop with the releases of whatever you installed.
That's generally what distro maintainers are supposed to minimize for the end users.
I see people recommending Arch for newbies, who maybe just want to dip their toes. They're figuratively thrown into the deep end, and I just don't think that's a particularly good idea for most people.
Mint (or Ubuntu) is a perfectly good alternative to Windows or Mac OS for an easy and "risk free" experience. Most people are perfectly satisfied with a black box OS.
Not that Mint has to be a black box at all. There's plenty of room for hacking around, if you're into that.
What is this rolling release fiasco? Even Ubuntu, which I use now has a "release" (technically an pt-get upgrade), almost every other day. But I've never had it break my system. If you keep your Ubuntu updated a dist-upgrade works just fine.
I might try Arch again, but for now I'm sticking to Ubuntu.
What you describe sounds like the consequence of installing a lot of packages. Arch "prefers" when you strip it down to what you need, if only because that way you don't need to worry about too many version mismatches.
If you're looking for your computer to Just Work(tm) look elsewhere. However I stand by my comment about it being an outstanding learning tool for the curious & future sysadmins.
