Holliday, vyper, and paradox are all bugged and just disappear after you throw them. This was fixed a day after the old gods patch dropped but is back again since Rem was implemented.
Doorman doesn't do any damage.
Kelvin replaces your ult with "cancel frozen shelter" for the rest of the game...
Any ult that cast and throw a projectile (vyper, paradox, holliday) flat out do not work at all right now.
drifter and kelvin ults now transform you into that hero for the entire duration of the ult now and don't allow you to use any of your abilities during that time.
Seems like you cannot redirect onto enemy heroes through walls anymore if you predict where they are on the other side of the wall. The bolt will always just redirect towards the wall you're aiming at instead. Really hope this isn't intended.
