Hobgoblins should work fine and will give much better experience per kill than the werewolves (ravenous nightstalkers). However, you'll need to use a trick to deal with the Scourge Hobgoblins, which summon and can cause a mess.
You'll need the "Song of Highsun" song (around level 55, sold on a vendor in Firiona Vie in one of the buildings on the docks, or from Minstrel Eoweril in PoK library). When you sing this song at a mob, it will be teleported back to its spawn spot. Thus, if one of your pulls brings a Scourge Hobgoblin, simply pull the mobs up onto the flat area where you usually would kite, round them up before you charm, and get close enough to Highsun the Scourge Hobgoblin. Once the Scourge is teleported away, immediately use Fading Memories and then re-aggro the rest of your swarm. You can now charm a hobgoblin in peace and sic it on the rest. ^_^
Best of luck. I hope that helps.
(Note that I haven't actually used Highsun since returning to the game a few weeks ago, so I cannot say with 100% certainty that it hasn't been patched in my absence. However, I don't see why it would have been.)
