Next World Of Warcraft Raid Dungeon
Yes, this changed very very quickly after they put in the honour system because it turned out to be such an absurd grind that people simply couldn't keep it up for months just to wear a few items. But if they couldn't wear the items (some people sell their old stuff right away) they had trouble playing the rest of the game.
Now you only need the rank to buy items, but once you have them you can use them forever. This is why most rank 14 people just stop pvping completely and start doing raids and such (to get rings or other items).
