I had basically the same experience at my last job. I worked my way up on the service desk and after a few years basically everyone in the IT side of things new my name. I probably had more general knowledge of how to get things done in that place than just about anyone. Obviously I didn't have access to do a lot beyond general troubleshooting myself but I'd assisted with enough issues to know who to talk to and what info they'd need. Eventually I moved to an app support team and I hated it because it was more meetings and talking to vendors and trying to coordinate shit with other teams. I went from basically a constant stream of doing shit for people and getting their gratitude in return to waiting weeks on end to even get simple tasks through. My self esteem nose dived because I felt like I wasn't accomplishing anything and all I got from others was requests for updates on things I was waiting on other people to do.
