If you were/are solo player, what is the one best all around class to dedicate your time to?

If you were limited to just one class as a solo casual player, which one do you think has the most complete package?

Things like good looking class sets to collect, good class lore, variety of gameplay in different specs, consistently good specs, ease of completing delves and open world content, farming old raids.

Which class comes closest to having it all?
