X-E2 question(Should i replace it with something else?)

You have an excellent body and lens. If you're interested in photography, keep it. If you're interested in street photography, the longer reach will probably give you some comfort as you learn. If you have to spend some money, buy a used xf18. The AF is much quicker, the wider lens will expand your dof, good for indoors and street. Spending more money on a "better" camera will bring nothing to the table. At this point in your development, it's what's behind the camera that's the primary variable.
