Do healers have a place in PvE?

[Escalith]

Fates aren't only hate based.

There are alot of things you can do that allow you to get gold.

Tagging a boss first = Gold (You literally don't have to do anything else)
Tagging 20% of all mobs = Gold
Spamming Instants on ~ 30% of the mobs for 50% of the fate duration = Gold
Spamming Aero on a single mob till OoM = Gold

Of course you can try to heal, but that means you'll have to kite a ton of things usually.
Or you can spam other spells, but Aero is the least mana intense.
