actually you need to hider your summoners vs them, vs Natazga you need to fight hte board, but not with your summoner, vs Saturos you just do fortress build. Wall on (a4 or F4) to form a choke point with your initial wall.

no frick is actually extremly versatile summoner it can play a variety of strategies, it has good assasination tools, but also can toe vs toe on the front and si good at general pushing, he is even good at playing defensive. Thats why is one of my favorite summoners, I like summoners that are versatile in their strategies.
