So I got the Ice Breaker back when Xur sold it, but I actually got given it last night in the nightfall.
Do I break down the maxed out one I have and fully max the new "earned" weapon so I am some how superior to the filthy Xur casuals?
EDIT - Ive tried burning it and showering but the filthy casual smell wont come off

I would keep both, give the other to a different class or character you have created. Make a character if you haven't made a second one yet. Icebreaker is not worth dismantling.
