localization is not relevant to OW2 right now, voice lines obviously not relevant to OW2 right now and obviously the same is true for the rest of that list with the sole exception being art assets of which that is a days work for 2-3 designers because they are not redesigning something they are simply editing existing work which is actually a pretty easy job.
If you think this takes time away from OW2 you are delusional. There is no other word for it.
