You can't do tucker's any thing by useing hordes of minions, It's not that you got beat by mooks in an appropriate level encounter, it's the fact that 5CR worth of Kobold can send your level 15 party packing.

I agree with the actually useing Kobolds, primarily because of their shifty ability.

The point of the encounter is at the end you can flip over the DMG and MM and show the hard math on the CR of what they fought, It's a learning experience/thought excercise not a campaign encounter.
