Hard and steady rule for Gemming~
Yellow socket- pure Def 16 or 20 def, or 8/10def 12/15stam green
Red- Dodge/stam parry/stam agi/stam exp/stam
I have no clue why people come on here asking for help and don't take solid advantage of thier professions. You are a BS you are leaving 90stam on the board or 900 HP's!
You are a miner, a few hours and you have an additional 60 stam or 600 hp's.
You say you want to raid, little thing make a huge difference.
Your dodge is fine you need more stam and you need to work on badges to replace that cloak. The 25 badge is still one of the better ones in the game. Every other piece looks fine.
A few changes and you are at 33k unbuffed and very hard to hit. Best of luck.
