Bellular the WoW youtuber have a good video showing BfA transmog sets, he starts with questing sets then dungeons sets, which for me are more interesting than raid sets.
Blizzard started adding dungeon sets since Vanilla, back then it was all about the stats and there is no transmog and yet the sets looks nice, they don’t look like a clown suit, Then Transmog system was added in Cataclsym and with it Blizzard started caring more about questing and dungeons transmog sets.
Now with BfA; it seems that Blizzard worked harder to provide good looking questing and dungeon sets, and it worked to provide 2 group of sets, one for the Alliance and the other for the Horde, both looks nice.
Legion questing sets are … well ugly, take a look at this mail set, i didn’t like it, while BFA Kul’tiran mail set looks much better, i can see myself using this set a lot, the same for cloth/plate/leather sets, in the Zandalari side the Horde players will find a lot of golden sets, i wonder if these sets are faction locked? i hope not.
The same thing for BfA dungeon sets, they look nice, better than Legion IMO, of course it all depend on your taste, you may dislike all these sets.
One more thing, Wowpedia have a list of all green sets, you may want to check some of them.
