Avoid Dexterity; it doesn't really work for us. Too bloody easy to hit something the size of a barn, I guess.
Instead, take your "Lv80 Armor Scales with +Tooth and Claw, +Strength, +Dexterity" and change it to "Lv80 Armor Scales with +Tooth and Claw, +Strength, +???," where +??? is a resistance targeted toward your most common prey.
As an example, a very large percentage of the damage dealt by non-WA mobs is Crush damage, so a set of "Lv80 Armor Scales with +Tooth and Claw, +Strength, +Crush Resistance" would probably be a good idea for a first set. If you prefer terrorizing the WA, replace "+Crush Resistance" with "+Blight Resistance," and so forth.
Also: load the wing scales with +Speed and +Velocity. You won't regret it.
All of the above is just my opinion, of course, but I hope it helps.
