- A Healer with the ability to keep the party alive should not be marked as HORRIBLE healer like someone implied, because their job is to heal, not to DPS,end of story. As long as the party is alive and kicking, they have fulfilled the duty. They are ORIGINAL Healer.
- A Healer with the ability to DPSing as much as they are comfortable with while topping the whole party up is an EXCEPTIONAL Healer.

Long story short, you DO NOT expect Healer to dps or call them HORRIBLE for not doing so, just because they are uncomfortable. Any DPS on top is just a extra bonus that set those who can apart from the rest, making them standing out as an Exceptional individual. And if anyone push that DPS duty upon healer while they are clearly not confident in doing so, you are a jerk and deserved to have a boot up your butt.
