http://www.wowhead.com/item=34183/shivering-felspine - Assuming that a survival hunter is wearing these weapons with both socketed with delicate crimson spinels. Apolyon: 35 stam, 30 agil, 16 crit, 12 haste, 164 ilvl --- Felspine: 38 stam, 32 agil (+2 ap socket bonus), 22 haste, 154 ilvl. Both weapons have 3.60 weapon speed now. Apolyon has 44.66 damage per second. Felspine has 44.43 damage per second. Trade off - Felspine to Apolyon: 3 stam, 2 agil, (+2 ap), and 10 haste for 10 ilvl (154 < 164), 16 crit, and 0.23 damage per second. Now, I'm no master at this, but you guys tell me what you think is better for PvE.
