For the time being, Blizzard was going to reset the honor points and marks for expansion, they mentioned something about adding new PvP gear in the upcoming patch encourage people spend to their honor. If you wanted to gain gear upgrades through honor at level 70 when Wrath of the Lich King arrives in a few days. Maybe it doesn't hold your breath. At that moment, Blizzard has stated that Season 3 rewards won't be available for honor points and that Brutal Gladiator items will retain their rating demands.
   For one thing, at level 70, there're no plans to make Season 3 gear available through the honor system, due to the want of new rewards for Arena. since all honor gear available through vendors are two seasons old, all current level 70 rewards will remain as they are. The personal ratings requirements for Brutal Gladiator gear will also stay in place, pointing out that the gear will last well through the Northrend leveling experience.
   For another, level 70 Arena is dead unless it becomes some strange new form. of twink PvP. I highly doubt that because getting to level 70 requires quite a bit more time investment than, say, Level 29 or 39. It is also the lowest level of the next Battlegrounds bracket, which means that players staying at 70 will be at a great disadvantage in any given Battleground. That's quite opposite the twink philosophy, which I believe should guarantee the death of level 70 Arena play. There are also no end-of-season rewards for level 70 at the end of Season 5, so players' best bets for PvP gear are Season 2 Merciless Gladiator items.
   In my own viewpoint, Blizzard should hand out a set of basic PvP gear to everyone beta testing when they raise the level cap so we can really give it a whirl in a more balanced environment. As a matter of fact, the Season 3 and 4 gear you see now will likely be the last pieces distributed to players. Most players will be leveling to 80 and others who have yet to hit 70 will skip past the gear. Although ranked matches at level 70 will continue to exist, the payoff will be so slow - players will need to wait one week in order to get Arena points - it makes no sense to farm Arenas for leveling gear. Since ranked matches will only be at level 70 and 80, it means that players will need to stay at level 70 for a long while just to get some gear that will eventually be replaced.
   It goes without saying that level is a heated topic at the moment, most of the player in the World of Warcraft take more notice of it. Not to mention, some one spend day and night in leveling to their desired goal, but it is hard for everybody do that. For most the time, we, provide more useful and beneficial tips and guides for them to upgrade their levels.
