Yeah… you can find alot of good troops mixes in this game. I like to advance with 2 or 3 foot nights with a royal archer with multiple support as a covering unit, The orcs would just smash themselves against it and get decimated.
And foot nights are excellent for urban warfare. My level 5 foot nights in a castle are rated at 31 melee, and 30 defense.
I also have 2 rangers that are fun too use with the hit and run tactic. The war eagle helps out also. Almost forgot mass heal is a life & timesaver.
