i have only 2 HW's at level14 and they are great for defense, but how affective are they in a larger number? If I upgrade 4 or 5 are they worth the I-Cores? if so what is the difference? anything will help. I know having 2 is good, just want to know if more will increase base defense or is another turret better? anyone please?
