Easiest Healer to play?

[select20]

I have never healed before in an MMO. I would like to learn. I have been tanking almost exclusively for probably 15 years.

Also, if I could ask two more questions so I don't have to make other posts.

What is the hardest and easiest Tank job to play and/or master?

What is the hardest and easiest DPS job to play and/or master?

Just planning out which jobs i want to finish leveling. There are nights when I feel like playing something challenging, other nights, I just want to chill. I would like to have options depending on how I feel.

Thanks ahead of time for the replies. I'm constantly blown away by how helpful and polite the community is here compared to other mmo's I have played.
