Any Class What is the most braindead build?

By braindead, I mean least effort to maximum effect ratio. My first thought was paladin, but paladin doesn't have any damage.

 

At a base level, any build where you just cycle the same attacks.
In practice I think epoch (or more general but epochs the most efficient) tierstack. Because you hold one key for damage and youre done.

If you have any group of mobs (like world events) its just shaman though lol
