I found this site to be interesting when you wanna know how good your r9T3 weapon stats are (Note: programming involved, but you can just view the results).
*All casters' weapons (Wizard, Psychic, Cleric, Venomancer, Mystic):

-Requiem (magic sword, wizard)
-Apotheosis (sphere, psychic) --> missing max mag atk
-Sanctity (glaive, cleric) --> missing max mag atk
-Etherwalker (pataka, venomancer) --> missing pdef
-Reincarnation (wand, mystic) --> missing max mag atk
*Blademaster, Barbarian, Seeker:

-Dervish (dual axes, blademaster)
-Hegemony (poleaxe, barbarian)
-Samsara (sword, seeker)
*Archer and Assassin:

-Firmament (bow, archer)
-Adversity (daggers, assassin)
It's not super accurate for Cleric, Venomancer, Psychic, and Mystic because we literally have 4 addons that have range, while other classes only have 3. The program omits max mag atk for Cleric, Psychic, and Mystic. It omits pdef for Venomancer. I'm using Wizard's data instead since it's the closest magic weapon with same addons (just no max mag atk for Wizard).
For me, my wand is wand #757 (top 45.49%). It's better than most wands, but not the best which is what I feel all this time. However, rerolling costs a lot of money and I just don't feel rerolling it to get the perfect stats. I'm happy to just have the weapon anyways.
