Even though I wasn't effected by this, I understand where you are coming from. The way they are handling this is wrong beyond belief. Not only did they give you flat out false information about the game not requiring more than 25k Honor Points, but then they told you to post about it on the forums. It's essentially saying, "Go to the forums. If enough people have the same problem, then we should do something about it. If not, you can still play the rest of the game just fine."
They hard capped your Honor Points because apparently having over 25k Honor Points was not intended in the functionality of the game even though we've had the capability to so since the Honor Point was introduced.
I had a sinking suspicion that the newest PvP vendors had those items, and now I'm almost certain that's what happened.
