The big question is how often +122 Crit rate will make you crit, like Turtle already mentioned.
So if your normal crit rate is 10% and adding +122 increases your rate to 35-40% so that every 3rd attack lands for a crit, then in that case the crit build would not only out dps at STR & ATK build, it would also make for a decent tank build with all those crits giving HP back while under Rampage effect.
And yes, the "/" means or. No Darklight armor is meldable, so I'm giving the option of that or a multi melded Savage Might Materia on your choice of body armor.
