He is talking about items you pick up while leveling...
I was lvling arms with the prospect of going fury for 5mans and farm at 60 to buy gear for pvp. So my goal reaching 60 was getting ok fury gear and ok tank gear.
Whrilwind weapon; get this as fast as you can upon reaching 30. I used this untill 55 where i bought devilsaur etc and had atleast some + hit to justify going fury
SFK: Ring from quest and ring that drops will last you a long time (stam + strength)
SM armory: head, legs and shoulder will last you a long time eventhough they are mail.
Hinterlands elite Q: bow, neck and trinket that will get you to 60
For fury i did alot of mara princess runs around 50 for Blackstone Ring
55+ you should do alot of BRD quest give XP and there is alot of BiS gear or nearly BiS gear that drops there.
At this point i also bought Valor belt, bracers and gloves (30 G total) + devilsaur set.
Specific items; i just remember wearing this cloak for quite some time
http://db.vanillagaming.org/?item=11858I wouldn't farm any instance beside SM armory before Mara princess runs tbh. I did most dungeons with all quests but never went back when no items dropped.
Also the Qs in AV give easy and fast XP. Might want to save those for 59-60
