well try grinding upto lvl 63 ~ 69 first , before crafting either Shark Aron epic set or Thanatos Epic set , grinding is much easier and carefree before lvl 63 .. so try to be a little less of a worrywart before then ..
when you reach 63 ~ 69 , that's when you put cards on your gears and stuff ..
i have a Ronan , lvl 70 with an SS stat .. lol .. not bragging tho , just saying that i , for one also experienced what you are having ..
