|Felinos in his DPS Discipline spec -- and Defender Illona. He needs a lot of defending.||
You And Your Bodyguard
I couldn't wait to upgrade my barracks and get a bodyguard for Draenor, because my main toon, Felinos, is a holy priest. While he isn't that easy to kill, it does take him longer to kill things, and questing gets tedious. I upgraded, grabbed Illona as my bodyguard but she seemed to die too easily, so I took on Delvar.
...and regretted it about ten minutes later.
It wasn't that he was bad at anything, but he talked constantly, bragged, and got drunk. He seemed the hypercritical sort -- as though following a (male) priest in a robe (dress) around was beneath him. Two bodyguards later, I figured out what I was doing wrong.
As with dungeons and raids, bodyguards have one of three roles: DPS, Tank, or Healer-damage. Illona was a tank, but I hadn't been treating her as a tank. Delvar was pure DPS, which meant that a lot of the time the mobs decided a live Night Elf priest looked a lot tastier than a plate-wearing undead Dwarf. Leorajh is a shammy who heals and does ranged DPS. And once I got THAT sorted out, things began to make sense.
So consider your role before you pick a follower
Falcos, my druid tank, ended up with Leorajh as a follower. He needs heals but he does NOT need someone for Competition Tanking (which was what happened when teaming up with Illona. Felinos, my priest, ended up with Illona because he needs someone to charge in and entertain the mobs while he heals and does ranged damage.
My hunters did better with tanks and melee DPS, and my warlocks seemed to do much better with melee DPS and the Voidwalker as a tank. I went with ranged DPS for my death knight.

You'll notice that you get reputation at 10 points per kill with your bodyguard. It takes a LOT of kills to get to the next stage. With the second level of honor, your bodyguard gets a new damage ability. With the THIRD leve, the bodyguard gets an ability that is useful to you...
Delvar can set up a "death gate" portal to your garrison
Vivianne can open a portal to your garrison.
Illona can use "guiding light" to summon party members to your location
Aeda can set up a summoning stone so you can summon party members
Ishall can bring a raven (mailbox) to your location
Leorajh can set up a garrison mission table for you
Tormmok can repair your armor in the field.
