There still is no real customization beyond your Bonus Stat points. Even if you have melded accesorries you are just melding as much main stat as you can get STR/VIT. (most of us dont have this kind of cash anyways)

Secondaries are rather meaningless at the moment, until the scaling catches up and we get esoterics/savage coil and actually have options.

Get as much Vit as you need to survive, and the rest into STR.

On the +side as tanks we probably have more stat customization options than any other classes at the moment, since we can wear STR accessories or Vit or a mix and match of both.
