The idea of this thread is to make a recommendation on what the legendary crafting priorities should be in TGT. Obviously this will to a large extent depend on what kind of deck you play, so I'll try to take that into consideration. As it is still very early in TGT to judge the meta, I'm going to make some provisional comments and create a list as it evolves.
At the moment the "obvious" pick would be Varian, but not everyone is a warrior. Yet :P
Strong class legendaries: Rhonin for Tempo Mage, possibly Eadric the Pure for Paladins, and Mistcaller for Shamans is currently controversial.
Of the neutrals, I am personally leaning towards Justicar Trueheart, which I've seen used to devastating effect in a few Warrior, Mage and possibly Shaman decks. Chillmaw also appears popular. I've also seen Gormok, Saraad and Bolf in play but don't know how effective they are.
I'm keen to see what other people think, I'll try to incorporate everything to get an idea of how the meta is shaping up.
NOTE: I'm just ranking TGT legendaries here as many people will already have the previous expansion must-crafts (ie Dr Boom :P)
