I am writing this cause I had no idea and I was looking up stuff and saw that Intact Mosaics can be used in place of an Inscription in the Forge. And its cheaper than Zerkers. So if you have Ascended Armor and Weps lying around you can switch them for under 3 gold a piece.
I love the Grieving gear. I have switched all my Ascended Armor to it. You can set up some really fun Builds for Fractals and Open World. I am willing to bet numbers will hold up in Raids too but I do not care about that. I care about fun. So For instance on my Necro, Reaper set up and Great Sword with a Blight Sigil. Scepter and Dagger in other slot. So I put a full rotation of Conditions on a mob then pop into Ghost mode and get huge burst of DPS and the blight rune procs on the Great sword and numbers flying everywhere. Ranger same thing longbow with Blight sigil and Axe and Torch drop full condi rotation on a mob and switch and boom things melt. Mesmer using Great Sword Axe and Torch same thing applies. You can now run pretty awesome Power Condi builds with very little dps reduction if any. No need to be restricted to any build at all anymore other than your raid group insists on Zerkers but as I said I am willing to bet the numbers are really close.
So if ya have stuff lying around check it out it opens up so many possible combinations. Oh and for runes I am using Adventurer atm
