Tales of the healer...you never heal anyone else than yourself...you ended the last one with 4 medals before the ending, how is it possible for a healer NOT to have th full 8 at least from healing?
You often does not buff yourself after dying.
You try, as a healer spec, to facetank 2-6 opponents at an enemy turret alone...damn...
Take a look at Youtube, and get some pointers from there.
I like that you produce videos man, i really commend that but you need to train and learn som more gameplay mate.
Keep practicing though
