Guild Wars 2

Im trying to think on the armour and weapion set im gonig to use in my tanky phantsam build. The buil focus on raw power and the a mix of toughness viat to give me as much survibility as possible (this is a WvW build mainly)

This is what ive come up with (all 80 exotics from crafting/orr)

Helm – Knights
Shoulder – Knights
Chest – Armageddon
Pants – Knights
Gloves – Armageddon
Shoes – Armageddon

Amulet – Emerald
Ring x2 – Emerald
Earring x2 – Beryl

Weapons
Sword MH – Knights
Focus – O/H – Valkyrie
Staff – Knights

With Sword/Focus my stat break down is

Power + 699
Precision + 328
Toughness + 580
Vitality + 264

With Staff

Power + 673
Precision +392
Toughness + 580
Vitality + 264

What i wondering is do people who also play tanky feel i should try and throw more stats into Viat and out say precision or a lil bit of toughness and if so which pieces would be best to do that with?

Any help would be awesome

Cheers!
