As the title.
I think Resistances are more important, because Resistance can support mutiple defense
and for some mechs that weapons are heavy, there are no many weights for Platinum Platings.
I think that's ok......
Yesterday I got 2 Premium Box legendaries in combo, the Physical Wheel and Viking Hammer
But they're useless for my mech, so I used them in a boost....
and I got many Premium items in 75T boxes
