Unless you know completely what you are doing on the gene level, if a species can have more than one desirable trait(phenotype) then it is a gamble to expect that optimizing for one will not diminish any of the rest. Somehow as a society we understand this, the team sports we create require a blend of abilities that are nearly impossible to find in a single individual -- we find this out after the fact when we get good at optimizing the teams for winning. In folklore/fiction the superheroes are only optimized on a limited set of abilities or if they are too super we throw in "an Achilles heel"/"a Kryptonite".
