As you see in onyxia use the rank system of vanilla with the feature there's no reset each week, but still exist the honor points because the client and as you know, now is just a cosmetic number. Since is obvious the great reset on honor when tbc comes out, i suggest the next options to use the honor points while them.
A) exchange honor points for gold
B) exchange honor to accelerate the rank climb (buying the achives)
C) exchange honor to comestics in a special shop
D) exchange honor for special consumables
E) All of the above but is by player's choice
