I cannot change troop trees. I can give this as suggestion but I do not think they will change it. So these changes are out of my limits.
Also when examining your screenshot I realized someone changed power calculation formula. It was not like this before. There was higher strength difference between tier-0 and tier-5 troops like 10x as it should be. Because 5 villagers cannot win aganist 1 tier-5 troop. I checked and see it is changed at 1.4.0 but I could not find who changed it. Asked info about this at office comunication channels but probably I will not get any answer (communication is not so good there). I am placing an image to show you old formula. Thats why players are losing high tier troops at simulations aganist even looters. However if we make this 10x like in old days probably it will be worse for snowballing but for better and equitable gameplay we need to change formula as in old days.
