Hi, can anyone tell me ,frost dk at Ragnaros(WLK 3.35) , dps go 20 strength on gems, or should i go 20 armor penetration , cuz , i got like 1100+ arp without any arp gems , i was wondering should i socket more arp gems to reach the 1400 arp cap , or just got what i have on arp , go 20 strength gems, which option would give me more dps, full arp or full strength ?
