I guess you could say it was a balance issue, but it depends on your viewpoint. To me, it was basic math gone wrong.
As announced on the WoW forums here, players are getting their honor downgraded by 30%. Apparently the massive surge of people with HWL/GM PvP gear got a bit of attention. I know there’s a good amount players in my guild with 4 or so pieces already, and one completely done, I believe.
I may be jaded, but I can’t help but think of the many times this has happened with insert_random_mmorpg_here. A bit more testing, or a bit quicker action would have prevented the fun the forums will have with this.
On the good side, maybe this means the queue to get in will be reduced? Muhahaha.
