I don't wanna have an overtly negative take, since I think running through Variant/Criterion is pretty fun. However I think in terms of long term staying power PvP does have a lot more value than V/C dungeons. To be honest though I don't think updating the look of an old PvP zone would have as much of an undertaking, especially since they are revamping all the old graphics so it would be a good time to go back and fix it.
