Apparently direwolves aren't a common tame amongst higher level tribes so they're uber good for trading- also essential for early game! Suck it up and go into the arctic for an hour you'll live! Probably!
Getting a TLC patch in March 2018 to add howl that will initiate the pack bonus for 5 minutes, will be able to sniff out players or creatures with less than 50% health, and will be able to detect explorer notes.
Vicious and lightning fast, the Dire Wolf is a great all-around mount for adventuring and attacking. I highly recommended to bring packs of Dire Wolves for any hostile situation. Whether it be kill Alphas, or raid bases, it's size, agility, and damage make for a deadly beast.
