I recently enchanted my weapon with Mongoose from Major Spellpower to increase my avoidance for tanking Brutallus.
I was quite surprised to see that this enchant was rated 'zero'. Not only was I surprised that it was rated 0/10, but "Enchant Weapon - Greater Agility" which gives 20 agi was rated a 7/10?! Mongoose can proc 120 AGI which with kings comes out to around 5.5% dodge, which is kinda sick when main tanking.
Very curious as to why Mongoose is deemed worthless. I have threat coming out of my *#& and 5.5% dodge is a lot more useful than 40 SD. (Which is about 12 TPS.)
