It is a player issue in the immediate sense. However... it would be silly to pretend 3E, in its design and marketing, was neutral. The edition gave min-maxers enormous room to operate and the surrounding community developed a substantial optimization culture around it. So yes, people can do this in any edition with enough options and mix-and-match potential, but that misses the point. What made 3E distinct was how unusually deep the roots of out-of-context optimization became, to the point that it overshadows the system's actual selling points.
