It's probably way too optimistic to hope they take a page from Blizzards book and change things so that any % based stat (mitigation, acc, evade etc) be based upon your characters level and not necessarily the amount of any given stat.

That is to say, 500 parry to a 50 tank might equate to a 50% parry rate, but 500 parry to a 55 tank might only be 20% parry rate, essentially forcing you into better gear to bring your rate back up to "endgame" levels. Otherwise we'll eventually just cap out on everything with "crap" gear and stats will become even more mundane as the only thing you need to worry about is your main stat.

Or, perhaps they just have a hidden mob stat that your parry (or w/e stat) will need to roll against, which is a lot simpler, but think about who we're talking about here.
