So, reading the thread for awhile, I kept seeing people mention blender, new costumes etc. Finally got crafter to level 20 and understand now. I have 4 extra costumes currently so figured I'd try, thankfully no bad luck on first time, got Ms. Marvel Binary Costume. No other purpose for dupe costumes, besides doing this right?
Not really, unless you want to keep a different set of costume affix's on one (one damage focused, one defense focused).
