We must play at very different tables. I cannot think of a time when I DM'ed or others DMed and allowed for a single use solution that only a wizard could solve. The designers did not cast out the martial or pull up the ladder on them. They looked at and applied the martial tropes people have for each class (especially modern-day cinema), and then tried to build a class around them. Old school tropes like Conan and Lancelot and Aragorn are in there. In books, Forgotten Realm's characters like Drizzt and Wulfgar are in there. Newer cinema versions like Cap'n Jack Sparrow and John Snow. Female tropes are in there too: Katniss Evergreen, Brienne of Tarth, Arya Stark, Xena the Warrior Princess, Holga... The list goes on and on. And they did a pretty good job at letting people create their characters in a resemblance fashion. To say otherwise seems shortsighted.
