I think more legendary powers from items and maybe even set bonuses will be unlocked each new season and once the season ends they’ll be made pemanent for non season too.
If it’s gonna be like that, than it will be a really great addition for all SOLO players.
As for the 4th cube slot to be permanent after season ends I agree 100% and support it too.
As for other than the follower changes I can’t believe there’s only gonna be changes made to wizards, DHs, Necros and WDs.
I hope other classes will also receive some love too, cause a lot of people expected 2.7 patch to be HUGE and from what I’ve seen right now it’s really underwhelming when it comes to overal balance changes to ALL classes, BUT I highly apreciate all the changes made to Followers and giving them all item slots and am eager to test out the new emanate system and hope that devs will continue to add more legendary powers and set bonuses support to it.
