Except the crucial difference is that you cannot use these HC items in arenas; as you can with BLF.
Back on topic though: In my opinion fairness must be maintained, if other rogues can no longer get their hands on BLF, outside of marketplace that is, then the rogues that got it before the change should also be barred from using it. The way I see it, this change is either: A.) A preliminary adjustment preparing for an overall sweep of BLF, or B.) A lame band-aid fix that does nowhere near enough to fix this mongo ****. Pre-wipe Warsong had class restrictions on BLF and AT was also very selective on which PvE items would be made available, so really there is NO reason why such a problem should still exist. If they should continue putting this off, then prepare to see constant BLF-carried R1 rogue comps. RIP PvP
