"Enchant Weapon - Exceptional Agility" (Permanently enchant a melee weapon to increase Agility by 26) gives a score of 0. You suggest Enchant 2H Weapon - Major Agility (Permanently enchant a two-handed melee weapon to increase Agility by 35) as a replacement.
Why go from a score of 15 to a score of 0?
Also, Arcanum of Toxic Warding (Permanently adds 25 nature resist and 30 stamina to a head slot item.) gives a score of 0, while you suggest Arcanum of the Stalwart Protector (Permanently adds 37 stamina and 20 defense rating to a head slot item.) with a score of 15.
I don't see the Toxic Warding enchant any more useless than the 20 defense from the one you suggest.. since the last thing a feral druid would need is defense.
"Enchant Weapon - Exceptional Agility" this will be fixed in next few days. All Arcanum enchants are fixed for feral druids, Stalwart Protector still has score 15 since its the best enchant for tanks for most fights atm .
