I healed in BC and Wrath, and am accustomed to having tank healers and raid healers primarily assigned before an encounter. I took Cata off and have recently started healing in a raid environment again. My guild doesn't assign healers though, and we're wiping on really easy fights like 10M normal Feng because people are dying from, in my opinion, lack of heals. When I mentioned it they reacted like I was an idiot. My question is does the general population just wing it or is there some structure in place that my guild is lacking?
