It’s not what it used to be and it’s not what it should be. There’s really no excuse for the nerf. IT was really strong in beta, but not any stronger then vet’s voice later on. The fact vet’s voice is in the game now is plenty of proof it was fine.
And yet, it was nerfed to the point it can’t knock down a pox walker. For awhile (did they fix this?) Psykers literally couldn’t complete the ‘push guys off a ledge’ penance because of how little push it had.
Here’s a video from closed beta cut to the moment the ult is used. It would have done more if they backed up, but they get most of the right hand side. If it links bad go to 2:21 (EDIT, there’s another at 9:16)
And here is a topic I made last December when I gave the game a try again and compared the two in a video.
