u/Arxade

Haven't seen anyone bring it up yet but I think it's a pretty important part of the update to mention. KR will not get any new voice acting at all, while EN will not get voice acting for the main story (but stuff like combat lines and costume interactions should still be voiced). I'm guessing these are cost saving measures due to the long maintenance, so hopefully these are just temporary until revenue picks back up again.
