This isn’t breaking news or anything, but for those that do not know, honor points and justice points WILL transfer over to Cataclysm, so start saving those points now! When we reach level 85, we will be able to use the points we saved from WotLK.
The cap for Honor and Justice points is 4000, and you cannot go any higher than that. Some players may have more than 4000 points, and that easily could have happened when the currency change went live. I myself had over 5000 honor points due to a stockpile of BG tokens.
Do honor points and Badges roll over into CATA, or do they reset to zero?
Yes, honor points and justice points carry over into cataclysm. Stock up now!
Players that have over 4000 cannot earn any more points until they spend enough to go below that total.
