Herding can be fun, but there are restrictions. You can only herd creatures that can be tamed, you can't herd them through moongates and you can't give them commands other than 'move to [targeted location]' or 'follow [targeted character]'
I have herded Reptalon away from Miasma's area - though you can't move Rend! I have herded Fire Crimson/Platinum drakes away from the Balrons at Chaos in Ilsh and Ossein Rams into the corridors in Deceit further from the Lich lords. The last two to make it easier for taming them. In the past I have herded Unicorns left over from Oaks in T2A to Delucia, giving red champ scouts a bit of a surprise, but never more than 3 and you can't do that anymore, the champ area clears once the champ dies now, and there is less 'scouting' champs done anyway.
My most fun 'herding' adventure was this one:
