Its a greataxe mate, think of it this way noone gonna refine JM, people will only refine weps like greataxe ect im sure someone will beat a JM's DC with using only 2-3mill in refines buying (ores/axes/dc items for refine), they will need to be lucky tho will still change the market.
Greataxes go up in prices - JM devalue price. it's inevitable If they add weapon refine think about it.
I would pay more for a Luck7 Greataxe then a JM around 40m if i had it.
luck7 hits high end dc everytime means u lvl x3-4 faster then others Uncompeteable. luck7 = ur king of server
Already spent 6mill on benes on my Dsword ended up on luck 1 again

Velocity wep will always out perform a JM once luck7 tho.
