TW/FA: Roll as Brute or Tanker?

[Zeraphia]

I'm seeing very great potential here for this combination in that it can AE farm and do superb AoE damage in regular gameplay and could "tank" decently well when IO'd properly and exemp very well. I'm just not totally sure which particular one I should roll, the Tanker may allow me to fulfill Tanking roles on teams however I'm not sure FA is going to say, allow me to tank LR or have the consistency in damage that Brute can. Brute also may be durable enough for this not to be an issue. As I've said, I'm unsure... TW does shore up a lot of FA's shortcomings with its knockdowns and the Melee defense so the combination itself is solid but I don't know if I should really roll as Brute or Tanker in the case of a general game consensus. I'm sort of leaning more toward Tanker but I want to see some opinions on this.
