Don't know which class to main..

Hey guys,

I basically enjoy every class so it's so hard for me to stick to a class.

I really wanna try to heal this time around. Never done it before.

These are my characters that I leveled as of now on octo:

This is what I have now

Shaman – Level 20

Warlock – Level 6

Paladin – Level 17

Druid – Level 20

Hunter – Level 17

Priest – Level 7

Warrior – Level 2
