So....whats the problem? They're just artificial numbers, they rise in ilvl to show a difference in power on the gear, and it inevitably happens that it'll rise much higher than whatever max level is due to the fact so many patches with new sets of gear comes out before the next level cap comes. This seems like a pointless task that'd just take away from more important things to improve on, you'd have to scale every piece of gear in the game and every single mob in the game to match the new level of the gear if you're talking about reducing it's power.
