Instead of the current rules or as an alternative ?
Not sure

The Dwarf army seems to struggle against cavalry
So i was trying to come up with a solution, a unit that can charge cavalry.
My friend has about 9 gyrocopters in his army (they need basing and painting)
The stats i did are the same as giant eagles, plus 1 shooting attack for 10 points
We will play test the new unit, and see if it's any good
