I went through this problem in CM a few times when me and another tank were low on ilvl and health. I called them tunnel vision. Because their minds are only focus on the goals and forgot what it was or how it feels to start from the bottom. Honestly it's kind of good you had to go through this experience. Why? Now you know how to treat players especially the more challenging roles like healers or tanks. Use this as a reason why you should treat people how you want to be treated and share tips and advice as you wanted it back then.
