Interesting idea for primals to be reforged only to primals… I think a lot of players would like that. They could make the recipee require more materials to be more challenging but still rewarding. Another idea is to make a primal puzzle ring guaranteeing you another random primal just like the first time you complete a 70 rift. It’s not that game changing. I 've only found 3 primal puzzle rings in my life.
I would also like to see a new gem like Legacy of dreams or a new set of rings allowing a full primal build to be viable for all those primals that we were hyped once they dropped and they turned out to be Blackthornes, Butcher’s Carver, Eye of Etlich and Gladiator gauntlets. Maybe a middle tier build, that would be fun to play.
