I havn't ever seen any green from MoP that fits on lvl80 char (wtb if any, maybe I'll twink a lot like all those scrubs).
I found some char on my realm rezzed up by SoR to 80 -

Dodge 10.82% - 383 rating = +5.64%
Parry 32.34% - 289 rating = +4.26%
That parry comes from strength (at this toon its 1036). At lvl80 there are not much items from MoP with strength. When I calculated it when MoP was about to come live it was like.. 1700 str or something? Plus fact that it's before diminishing returns makes me even more doubtful is it possible to get 100% avoid.
I'm currently leveling 2nd paladin, maybe I'll check it one day.
edit:
Ofc yes, reforging. But for soloing purposes I feel haste>crit>mastery is way more powerfull than reforging into avoid (mastery due to using server-lag with sotr-reduction buff, not sure if it's still working - I mean vengeance is capped so you wont get millions this way as it was shown on few videos, but it may work to get more vengeance than intended)
