At level 40 you gain access to "Heroic" Dungeons. These are harder than Elite dungeons and have a chance to start dropping Equipment! They're a pretty easy way to upgrade your main team, just equip the equipment! You can easily trade these between characters.
You only get 6 different types of gear. Way easier than WoW, right? I don't know if I actually want to go into listing all the types of gear because that is a lot of work and I didn't get a lot of sleep last night, sheesh.
I am MT characters don't wear shoes or pants because, look, if you could get away with not wearing them, wouldn't you also not do that? I'm sure not.
