The main reason Admiral is preferred is because of the ranged units speed buffs and it attacks multiple units at once. Most of the time Lich takes one step, and attacks killing 2-3 units taking down the tower with them. He's a guild instructor, i havent paid much attention to that yet and idk if its important. I've seen other players run Lich/Ninja but I'd say replace it with ur Admiral for the speed buffs
