Ok, I bought the Swtor Razer product which gives you two dark green crystal (which is quite cool). The stats of the crystals +4 endurance What is the use of that? I can only equip it during lv 10-15 and thorw it away? Is it possible to upgrade or replace one of the crystal to lv50 ones. I am willing to pay the money that require to buy lv.50 crystal. What is the use of that crystal? Just install onto lv10 equipment and run around the imperial fleet just for showing off?
