They have yet to comment if INT will have a regen component at all. Reading this post, combined with info from Blizzcon, I am leaning towards INT no longer providing regen, and %mana restoration effects changed to work off Spirit.Originally Posted by Twintop
Also, INT will have a lesser effect on mana pool. All in all, healers will need SPI to survive. The question is: What will the playstyle be like? Are we going to have the same twitch/blanket style that we do now, only with less regen? Will have to wait for BETA for those questions to be answered.
