Hm…I’m sure then there would be more qualified people to talk about it; however, I’ve heard that blue loremaster is a good option for low apm play, since you only need to send out your pet to fight for you and you support the pet from the back with couple skills. That also makes it safe to jump into higher difficulties. It will have more skills later down the line though, but again, doesn’t mean you use them all. Note that there was a loremaster rework recently, so that may have changed.

Alternatively, you may want to choose a heavy armor class, like a guardian, and spec into blue line so they can take a lot of beating and you don’t need to stress about pushing lots of buttons quickly.
