Order Hall Champions in World of Warcraft

There are 8 champions in total for each class, but only 5 can be active. As with the garrison followers in Warlords of Draenor, you must deactivate your excess champions if you wish to start a mission and you have over 5 active champions. If you wish to reactivate them, you can do pay 250 World of Warcraft gold to activate one per day. Every class has their own separate set of champions, since they are all related to lore.

The best way to get My Champions
As soon as you complete the first set of quests after gaining 325 artifact power, you will receive your first set of champions. All the champions will come from the order hall campaign, after you reach level 103, you will be able to return to your order hall and complete a second quest chain for the campaign, which will allow you to unlock two more champions. The rest of your champions will come from naturally completing the order hall campaign.

The Data
Total Missions: 52 (I condensed all the "Investigate X Dungeon" down to one, as they're all the same and you can only have one up at a time).
AoE Counters: 40
Interrupt Counters: 28
Dodge Counters: 23

As a side note, you probably want to avoid having the solo-spec be the same character as the solo-counter as using that one in a mission greatly reduces your options for other missions. Therefore, you want 2 of your champions to be AoE counters, then a 2/1 split of the others. Since the spec is completely random, you just want to go 2/2/1 however is best.

If you're using one, it's because you want the 50 Gold and 100 Resources you get per world quest - it's a massive liability to mission success rate to only have 4 real champions. I'll note the grouping for 4 if you need the resources anyway.

The best way to gear my champions
The second slot is unlocked as soon as they hit epic quality. Champions have the option to unlock equipment slots as they level and grow in rarity (in the same way followers did in garrisons), once a champion hits rare quality, they will unlock their first equipment slot.

In order to prepare them for battle, you will need to find some champion equipment to arm them with. You can find it through the following means:
Missions in your order hall
Treasures
World quests
Emissary quest rewards
Class Order Hall advancements.

The items that are available in-game fall under a number of categories, they each have a different impact on a different part of the mission process.
