Tail spike is bad... Almost all of your damage comes from your weapon damage. Just to give you an idea the argas ring with 14 attack power barely wins out over
Bronze Band of Force - Item - World of Warcraft. Weapon damage is everything. Even as a stat stick in your OH I'd take something that swings faster and gives decent stats with hit, like
Balanced Heartseeker - Item - World of Warcraft. Missing a offhand white is going to yield a lot less then hitting with 2 more attack power.
The cloaks are 6 and 6 or 7 and 2.
RFC nets 6*2+6=18 attack power before any passive increase.
Glowing nets 7*2=14 attack power before any passive increase. And 2 stamina
Take the attack power and gain stamina from something that doesn't have the option to give attack power, like AGM.
