Human Warrior Rune and Trait Suggestion Plz
Check this one out: http://www.guildwars2guru.com/topic/74697-build-sonic-boon-shout-greatsword/
Though if you want to be more support/tanky use Knight gear only and use Rune of the Soldier (extra vit/tough + removes condition with shout skills)
Also, you don’t have to buy the book to retrait later. you can simply click retrait at trainer.
Divinity, but mad expensive.
Ruby is cheap and provides, arguably, the most DPS. (Scholar argument)
Honestly, I would just go full ruby as it is pretty much the cheapest and gives you a lot more DPS. If you can, later on switch to Full Knight w/ ruby as that will give you what you seem to be looking for.
Tankiness w/ DPS Traits?
I mean, you could add some into defense I guess…? Look around the forums and see what you like.
I would not suggest going Sonic Boon.
It is probably not what you are looking for.
