Quick question, how simplified was that example you gave? Mainly, I'd like to know if most items will have custom restrictions/possibilities of the stats they get. Even if the lists are much larger than your examples of 2 and 3, is each random slot 'designed' as part of the item, or is it more often that they're truly random? If your example is accurate in kind, just not in scale, then perhaps calling these slots/chips "random" is a misnomer, and may be causing undue confusion/misunderstanding. I think the term "variable" chips/slots would better in that case. Random makes me think it's... chaotic, unpredictable. Variable makes me think it's mutable... and more elegant somehow. I know it's just semantics, but semantics can mean a lot when it comes to first impressions.
