I was surprised to learn that patch 2.5.0 went live yesterday since Season 10 doesn’t start until March 31. But hey, that’s okay.
2.5.0 is mainly a “quality of life” patch, adding the Armory and other fairly interesting features. Other changes are not especially substantive, but some sets and legendary items have been improved. A new thing is Primal Ancient items, though I personally think they’re yawn-worthy.
