Not long ago, I discovered, that you can purchase full Ensembles in WoW, making gathering a set much easier.
It does cost 12 Marks of Honor though, so if you´re not that fond of PvP, go go do World Quests that reward those Marks as part of your daily routine. (Also, applaud for having a daily routine, I have none!)
You can then spend them on a full set of your liking. Lots of sets out there to purchase. I wanted to get my hands on some for quite a while.
The Ensemble vendors are in different locations, depending on which set you are after.
When you click the item you purchase, you simply learn every single set piece of it.
Happy gathering 🙂
