Stockpile your Triumph and Frost emblems

[Mystic]

Edit: Actually, don't bother stockpiling, the frost->JP cost inflation for items is a killer.

Basically, it looks like with patch 4.0 they will convert all triumph and all frost emblems to Justice Points. It is a 1:1 conversion, with a cap of 4000 JPs.

I'd say that is a pretty generous cap. If you have not been stockpiling them (been spending them on gems for AH sale, right?), then it is doubtful you can reach the cap by Cataclysm release. If you can garner 15 emblems per hour, and spend three hours a day, it will take you 88 days to reach the cap. I'm certain Cataclysm will be out before mid December.

So, get to grinding heroics via the dungeon finder and stockpile those emblems (JPs).
