I didnt know that mele fatigue doesnt increase when you are on a horse

I was thinking of how to stop them as Fomoria. Air doesnt work since they can easily get immunity. Morrigans scare the **** out of the thugs so I guess they work + wailing winds.
Otherwise about battle magic shadow blast didnt seem to be effective. Thugs niether.
Massed construction/bows worked allrighting unless sidhe lords buff with arrow fend.
Thugged Kings didnt work either. I guess if you give them high protection and set to cast hand of death might work. P.s Ghost grip might work as well. But I was wondering about army vs army situation.
