Thinking about the OP's question on equipment, I can't say if something is really missing but I certainly wish for more mundane equipment in general: real-world weapons from various cultures with quirks or minor interesting properties, different types of shields and many more armors, alternative materials for both weapons and armors, and various trinkets.
That was my wish already in 3ed, in general I find myself quite at ease with designing custom magic items, but completely lost with mundane items, so I wish there were just more of them...
