Guild Wars 2

I’ve been playing this game since launch and I know every class can do anything as it just depends on your empathy with that class.

However, after so many years the only thing I could find 100% sure is that
Ranger -> Druid is the best raw healing class. What about the others?

Let’s ignore gear, just pure skills and traits.

Thats difficult to answer becauses its dependant on what game mode your playing and what your objective is.

For example Druid is good for healing but a ele can also put out heals along with great dps and party wide buffs.
