if i were u i just climb orignally with good gears, keep up the climbing 1-71 constantly, u can find almost anything good.
either on hc or sc, i suggest u melee up til 30s+ to cast (i think this goes for any noncaster chars other then mage/gaurdian since they start with a good base mana/int) since im doing a monk caster atm im meleeing til the 40s in cata then solo myself from there.
with muting, magic luck helps boost the prefix not stats in my own opinion. say u mute a magical and a mystical u have a higher chance on getting a rare/mystical not a magical, this is just my opinion about magic luck, other then that mute freely with any same stats
