And yea if you have the materials/gold to craft a good 2H then by all means go for it. Make sure to get one that has LoH as you need it for survivability.
Honestly speaking equipping the GG bracer and having a good 2H weapon SHOULD put you at enough DPS to beat T6 comfortably. The rest would be up to survivability.
I did some group T6. At the moment I feel like a glass cannon. Probably two more pieces of Inna's would help a bit.
