I wouldn't count on it being fixed anytime soon You know how "highly" Blizz prioritizes low level balance, and the blue posts made it sound like they're more likely to redesign PvP than change the old gear for a higher base resi.
I just don't PvP anymore on my 80/85 untill resil it fixed. I dueled a 85 mage on my 85 warrior the other day. I died in 2 stuns. Currently I just PvE on them and PvP on low level.
