you should make archer towers that dont needs your own minions so you can defend base easier

did you try using the "flag" skill, it kind of works like what you are saying.

I've tried but they keep landing on the meadow, and not the tower.

if what i was talking about other thing not barbarians

i was talking about, that you dont need make walls and then towers, i was talking about that you make archer towers so you dont need minions
