Okey, so let's shred some light over this hype about Felstriker. A lot of people in the game that DON'T have Felstriker says that it's BIS till Naxx and that it's irreplaceable. I have been using Felstriker for a good 1.5 month and after all that time i can say that the proc rate is really, really bad, at it's best it can proc 2 times in 5 minutes and that's not to "overpowered" according to me. I think that the proc sounds amazing, 100% crit over 3 sec that's extremely good, but still, i do think that you'll lose damage due to the low damage of Felstriker compared to other weapons sush as Deathbringer, and especially for me who is a Orc with 5 extra axe skill. If you would ask me what's best between a Deathbringer and Felstriker in off-hand i would definitely go with Deathbringer, or even Vis'kag the Bloodletter for Human to use that 5 extra sword skill.
