GS defensive crit build
I got full berserker armor / accessories and GS I have 41% crit chance and with sigil of perception maxed I got over 51% I do fairly good since I have 17k HP with maxed trait line in valor…
I will try your build and see how much different it is.
Knight’s Gear is Toughness/Power/Precision. Which is IMO just what you’d want for what you describe (especially with Retributive Armor). Power/Toughness/Vitality (’Soldier’s Gear’) is available from the Vigil vendors and a few dungeons only but can’t be crafted AFAIK.
Power/Toughness/Vitality armor (not head piece) is available from Orr temple karma vendors.
WvW karma vendors sell Power/Toughness/Vitality upto rare level gear (armor, accessories, weapons, but no upgrades). WvW badge vendors sell exotic level gear.
This won’t hurt [Much]
Ring of Fire
Check out my Greatsword build in the sticky thread, it’s pretty much exactly what you’re looking for.
Is the Greatsword Power trait in the Zeal tree useful at all?
Well, assuming it stacks multiplicatively with other percental damage increases, it’s still only 4-5% more damage. It really depends on what you’re giving up to get it.
