The points everyone else has made are good, but I'll add one more:
Experts closing questions because they are familiar with what the answer would be and/or what it would involve to getmake an excellent stack-appropriate answer, is generally good and expected as long as the close reasons are valid.
In this case, experts looked at your question, determined that in order to give an actual answer that they would need more details, and then voted to close while we waited for those details. That's how we expect the system to work and we consider that to be good.
Specifically, experts in this case decided that "Your answer depends on lots of variables that you haven't given us" wasn't a satisfying or useful answer to give and that we should be aiming to provide actual answers which(which require more information).
RPG:.SE's Q&A format excels at giving specific answers to real, specific, well-defined problems. Questions that aren't that do better at other places.
