You obviously know how to code such a method yourself and i can't answer 
why for example Array#- doesn't work that way (had to learn that myself).

The shortest solution i came up with is

ar = [1, 2, 3, 8, 15, 15, 8]

p ar.values_at(*(0...ar.size).to_a - [ar.index(15)])
=> [1, 2, 3, 8, 15, 8]

p ar.values_at(*(0...ar.size).to_a - [ar.index(14)])
=> [1, 2, 3, 8, 15, 15, 8]

p ar.values_at(*(0...ar.size).to_a - [ar.index(nil)])
=> [1, 2, 3, 8, 15, 15, 8]

cheers
