True. The worg is just “gravy”, but absolutely not the threat. If you kill the mount, the stupid Caravan Raider just keeps running along after you and continues pew-pewing you and the wagon. Easier to kill, since he’s only moving at foot speed, but burning through 400k of mount health before attacking the actual threat isn’t good policy.
If you kill the rider, the mount runs away (and despawns). So absolutely not a valuable target. (They do loot out to Kor’kron meat, though. If you do kill one, make sure to go back and loot it after the caravan plays out.)
No, I want to chill the mount because all the mobility is there. If you just chill the raider, the mount’s still moving every bit as frustratingly fast as before. So, as I mentioned, I Howling Blast in the direction of the entire caravan-raiding pile o’ badness while having the actual raider targeted so I can start hitting him as soon as I can. Since HB is a cone AoE, it hits both if I’m facing in the right direction, getting me the movement speed reduction I need and infecting the raider with Frost Fever. Saves me a GCD in the normal opening rotation.
It makes a huge difference. I wound up defending 4 caravans with just my DK while grinding out the “150 of each” weekly, with zero losses (in fact, no caravan went below 50% health).
IMHO, slowing the mount is critical to success if you don’t have good ranged attack. This is where my marksman hunter shines: fighting on the run absolutely does not interfere with my DPS.
Or in one of those weird coincidences, a gunman is the best defense to a caravan, as well as the best attacker to it. The fiction works out just like real life.
ETA: Speaking of hunters, I found a weird little tip
about killing mounted Kor’kron Outriders at the meat farm. If you freeze trap them, the mount is frozen in place but the outrider is still targetable. And they stay mounted. And for some reason doesn’t attack very fast. So you can kill them at leisure, almost; just avoid the infrequent Explosive Shots they do.
Though it would be kind of cool if Stampede would summon a herd of cattle …
