Yeah, sometimes it does feel like that those drop a bit too often. While not useless per se, they’re definitely the least exciting ones you can get - unless you make a health regen build and have all other stuff in check already.
Feels like energy regen should be a “base” stat for all rings/amulets. Well, like it is on “white” items, basically. “of Renewal” is also an energy regen one, so you get three chances of getting it instead of OA/DA/AS/CS/etc.
Maybe make some of them not spawn on high level version of gear, I dunno =\
