I have been a healer for over 7 years. The biggest lesson i learned over the years, is everything is an experience. With experience comes the ability to determine the reality of the situation. If you keep at it, you WILL get better, and you will learn to see the signs. You will learn when it is in fact your fault, when it is the tank's fault and yes, those DPS that stood in the fire deserved it. And it was their own fault.

Understand one and only one thing from what i am trying to say - if a group wipes it is because something went wrong. I will not tell you what it was that particular time as i was not there. I will tell you this - if you keep trying you will know what it was. You will understand whose fault it is. If it ends up being your own fault - make it your mission to GET BETTER. If the fault lies with the tank, ASK (dont demand or dictate) that he help you out. If it was the DPS's fault... well they had it coming. :P
