Blizzard has been a real c-tease with Ashbringer.  NPC's have mentioned it since beta, and every time Blizzard talks about it they seem to only push it back.

There's more lore behind Ashbinger than any other item in-game.  It will be interesting to see how this pans out; I've been thinking that it may end up being the one thing that can defeat the Lich King.

Ashbringer at wowwiki.

He was, but an old quest chain in EPL has the player take disguise as a member of the Scarlett Crusade to help bring around his son, Highlord Taelen Fordring, to how corrupted the Scarlet Crusade had become.  The event culminates in Taelen's death at the hands of Inquisitor Isilliean (sp?) after a brief confrontation.  Tirion avenges his son's death by slaying the inquisitor and swears an oath to resurrect the Silver Hand.

He's not powerless. They stripped him of his rank and position and claimed they stripped him of his power. While they were able to do the first and second, but it is beyond them to strip him of his power, for it was not a power given to him by the leaders of the Order of the Silver Hand, but from something far greater. They merely taught him how to tap into that power. Afterwards, he was shown to still have the ability to tap into the Holy Light, since he maintained the true meaning of being a Paladin by staying true to his word in the face of opposition. His strength of character is well worthy of one who should lead the reborn Order.

Redundant.

Three cheers for possibly doing something with Naxx.

Oh and my main is a Paladin.

Melee:
Thunderfury
Sulfuron
Warblade 1
Warlblade 2

Hunter:
nothing confirmed yet

Caster:
Atiesh

Healers:
Atiesh


Why should they implement a new legendary melee weapon?
Atiesh: 4 Classes had to reach end content, before BC comes out, to battle for 1 legendary!!! this was maybe possible for 0.0001% of all wow players
Sulfuron/Thunderfury: were spread out for nearly everyone, because you had 2 years time to loot it. there were 100 of it on every server.
illidan warblades: same thing as atiesh, but again, melee weapon


i see no reason, why you should speculate about another legendary for the same classes, like everytime


there is still no
- shadowpriest legendary
- hunter legendary
- restor pally legendary
- restor shamane legendary
- moonkin legendary
and nearly unreachable caster/healer legendarys in old content

why should they have plans to implement
a new fifth warrior legendary?


ya blabla retri pally, that doenst changes anything of the problem

With the Naxxaramas Patch, we learned that Lord Fordring founded the Brotherhood of the Light.  See the conversation at the table in Light's Hope Chapel for proof.  Something to the effect of "I will inform Lord Fordring and his knights that you are no longer here on friendly terms.  I'm sure that would be happy to see to your atonement"

Also, if you pay attention to the story he tells you learn that he never lost his powers of the Light.

So there should be legendaries for every spec for every class? and when Hand of Ragnaros was obtainable, Molten Core was end-game and all legendaries have been like that, casters were just unlucky for Naxx to be the final 40 man raid before TBC.
