I once thought about the notion of attaching ingrained Parry statistics into weapons ala Paladin Shields... but keeping the Parry stat in place as-is.

Currently a Paladin can stack Parry to, by virtue of rolling both Block and Parry against a physical attack, end up in situations where they do something to reduce physical damage for 50%+ of physical attacks. That is not too shabby, if I say so myself. It's not particularly helpful when the major threat is singular large hits(seriously, why aren't there more multi hit physical busters. Geez...), but it's neat to be able to reach those numbers. So it'd be interesting to let the other two tanks reach that ~50% threshold if they wish to but it would kind of step on the one actual mitigation advantage Paladin has.

Another thing I wondered about is what if SE put Parry on all Tank equipment the way Accuracy was on 2.2+ Healer gear? A completely free stat that just slowly raises as your item level does. Another aspect of better gear making you just a little bit tankier. Shrug.

Of course, none of this would actually fix the issue of Parry being underwhelming as a stat. There seems to be talk of reworking it in either 3.4 or 4.0, so there's that. I mean... nothing SE can do to the stat will make the current generation of players actually want to stack it, but one can appreciate their intent.
