I would Also like to inform you that different rarity level grant different bonuses for upgrades. When an armor is new use common rating until around lvl 10 use uncommon to lvl 20 and use rare above 20. Hint you can fuse uncommons to get rare and super rare armor - this allows you to obtain a rare in a shorter period of time; 2 hours to craft vs 1/2 hour to craft 2 uncommons, use a fusion stone, and possibly get a super rare. :)
