Making "everything" voiced would mean less money spent on other things.

While it would be nice to have a lot more content voiced, it is highly unrealistic to expect it.
It would also end up very generic. When I played ESO, there was lot in that that I found was voiced. But I also found myself hearing the same voices over and over and over again on different people. When someone is voiced here, they feel much more unique.
