Which legion class / spec is the most fun to play ?

[Istaria]

This is a question for players that could and have spent a decent amount of time in the beta/alpha of legion with more than one class and have been playing a number of classes and specs in the previous expansions.

In your opinion, which class / spec is the most fun to play and why ? In PVE ? In PVP ? For solo playing ?

At this point in time, I don't care for damage / healing numbers or perceived value in a raid roster.

Thanks in advance for taking the time to answer.
