It's an odd nerf as this hits LON builds the most which are almost exclusively used in solo laddering.
LON bomb for example gains alot from the 7pur since it's hard to gain pur with thorns oj everything.
LON doctors also. To the person saying this is because of group play I say no, it's a nerf directly to thtee of the strongest solo builds and it's really disappointing as that was this items unique quality. This nerf drives set dependency even more. The opposite of what most of us want.
