If I'm understanding your original question properly then I suppose what confuses me is why healers are typically played by extremes like super lively and polite people or emo as hell and bitchy all the time and I've seen this a lot in my WoW days too. Another thing that confuses me isn't about people why main healers but more of why people are so afraid of it, because honestly i find it the most engaging and fun role to play and wish I had done it sooner.
