So I have been elemental for quite some time, and I really enjoy it. Over the past few weeks I had been asked to OS heal on a few encounters or when we had an attendance issue. However, last night my raid leader asked if I could take a permanent healing spot after he asked me to OS heal Hjin. I have no idea what I am doing and our best Shaman healer is MIA. I don't think i'll ever be able to compete with him, but I don't want to let my GM or anyone else down, What should I do?
