Gear at early levels, in general, is pretty useless (perkwise... fashion is another topic altogether I won't consider).
Through leveling up gear, Commons can give you: Your default perk + 1 of your other two options.
Rare: Any 2 of your first 4 perk options.
Heroic: Any 2 of your first 5 perk options.
Epic: Uh... Any 2 of your first 6 options, OR 2 of your first 4 options and 1 of your 5th or 6th options. I think.
Legendary: Any 2 of all 7 options, OR 2 of your first 4 options and 1 of your last 3 options.
I'll do far more than that. I'll provide you with a sorry end to your messy life.
Then I have no choice.... Damn the Wheel. Damn the world!
