Actually, the resolution increase is inconsequential. I have a D7000, however, and the mode (?) wheel is starting to turn too easily. The OP may be experiencing some of the same type of problems. This would be the reason to upgrade, not for a flimsy 8 mp. My daughter has the D7500 and it is a fantastic camera. If at all possible, I'd go for the 7500 over the 7200. Its low light capabilities are excellent as well.
Don’t you love it when somebody with no experience with a camera tells you whether it’s worth upgrading. As someone who actually upgraded from a D7000 to a D7200 I can say that there are several good reasons to upgrade. 50% more resolution for astrophotography is a good one.
