I recommend the duty roulette, Guild heist, while doing fates. You will get gold most of the time by just spamming bliz 2 anyways on fates so don't really need a party, and once you get into a dungeon the xp is great. I am biased though I really like leveling through dungeons even before 2.1 I think fates was a lazy mechanic but I understand why it was put into place. But do what feels best. THM can be a bore at lower lvls, everything seems slow and the damage doesn't seem like it is beastly but once you get to 30ish-40ish it becomes a fun class IMO.
