would dark/stone make a good scranker?
Really nice single target damage, subpar AoE damage.
If you value endurance this will not be fore you.
Stone has nice single target attacks, and Fault is awesome. With enough recharge you can get a good single target attack chain using Seismic Smash often.
Dark armor is probably not the best route to go. Maybe use an earth themed costume to cover that aspect since you don't want Stone armor.
Willpower for the endurance issues or Shield for the added damage and Shield Charge.
I have an Ice/Stone, which could be counted as a scranker, but it is just an awesome tank with really good recharge. It can use Seismic Smash twice in one Build-Up duration. I know Ice isnt what you were looking for, but you can get the same recharge from Shield and possible from WP.
YMMV---IMO

i got another conecpt in mind: Im wanting an earth themed char but stone armor doesn't seem that great. Im gonna color DA/ to make it look like sand. I was wondering how Stone melee damage stacks up against SS and EM.
