Enhancement Shamans 0% PARRY rate

http://www.wowhead.com/spell=86629/dual-wield

I don't support, has been so much that this is still bug, in the bugtracker no-one notices even ingame, shamans do'nt know that we should parry attacks The tooltip of the passive "Double Wielding" show us that we have certain probability to parry frontal physical attacks, but IN-GAME, my enhancement shammy has 0% of prob to parry, this is really annoying I cant fight against other melee classes, my dodge is working well but our parry rate must be per default 5% (it's minimal but is better than zero), but all the enhancement shamans have 0%.

You may look this bug a little "soft" but if you ask, a plate melee has normal parry, but the same bug of us in Dodge Rate = 0%, how you see that?; please all the melee classes have their defensive stats well just us, the shamans have this fool bug.

The first capture is from bugged server (frostwolf), the second one is for other MOP server (same patch )that I played and you could see obviously the difference; please fix this bug, I can't parry even an attack from a Durotar's Boar.
