Hi Hunter,
Not sure how much help I can be without seeing the HE list, but it seems like you've got a pretty solid tutorial army. Let's run down that list:
- Magic User = check
- anvil unit/units = check
- cover mechanics = check
- command abilities = check
- super special abilities by the rank-and-file = check
The only things I would say might be missing would be any Wild Riders or other cavalry/fast movers to provide a more traditional introduction to the charge phase (and units that benefit from charging). I would also mention things like monsters and artillery but last time I checked the Wanderers weren't going to be receiving any such additions in the near future.
Do let us know how this works out (and what the Highborn are bringing to the table
)
