I checked up the beta talent trees and it seems like for now lock goes back to Unstable Affliction as a spender and Malefic Grasping and Sow the Seeds is back also.
I wanna be hyped but while in Legion it was fun af, in BFA it turned out to be a horrible design :SSS
Oh, I loved Malefic Grasping
What i get from new trees , Malific Rupture is gone and now we spend Shards on UA and Seed
Good, the flow/feedback of UA spam felt better than malific rupture.
