for sure u shouldnt sacrifise the str of tank! i think u need 2 rings at all 1 for tank and 1 for the other two with chaos jewels! if u cant afford 2 rings imo go full str ring! ur tank is ur main will take advantage of str and the other chars will take advantage of extra health! u will lose damage at mage and rogue but ur main will stay good! other possible way is craft ur ring full nature jewels! useful for all clashes and cheap the same time! thats my opinion at all what u will do in the end is based on ur playstyle at all
