On the bright side,The help desk will definitely help you improve your communications skill. For example I just received a promotion, not for my programming skills this time, but because I'm the voice of my department. I communicate with all of our customers and other teams. They all know me, plus my emails are read by Directors and AVP's. So my promotion was easily approved.
Don't underestimate this. A good mouthpiece can get you a long way. Dealing with first line support is really a shyt job that gets under-appreciated, but you will learn how to deal with a large cross-section of society.
