Icecrown market place, achievement points and ilvl of gear
Achievement points really dont mean anything anymore since you reduced the ilvl of the gear available for points in the marketplace on Icecrown server.
There really is no incentive to get 5k+ achievement points.
But if you were to base the ilvl of gear available in the marketplace based on how many achievement points you get, then it will be worth it to get achievement points once again.
So lets say for example, if you have 1000 achievement points. Well then you can buy the ilvl 232 gear. If you get 2000 points then you can get the 245 gear. 3000 points and you can get 251. 4000 points you can get 264 and 5000 points you can get 277.
That was just a proposed estimate on how achievement points can scale for marketplace point gear. You can set it to what ever threshold you desire.
