What? You are wrong. You are still wrong. You either have perma dom or you don't. You either are or are not. That's not how defense works. Polarizing. Yes/No, not a matter of degree.
What? Where? Math? I showed you how 1% is 20% more attacks that you'd take than if you had 45% from 44%. What?
My reference with your link is that it clearly states that it may not be worth chasing the last 1-4% for soft cap vs what you have to give up. That is never the case with Perma Dom, because it is polarizing. You do know that if you have Perma dom, you can use it with the same bar you built up. When you don't have Perma Dom, you have to build the bar up. Yes/No; polarizing. Whether you're at 44% or 45% defense, you still have Defense. Whereas if you don't have perma-dom, you DON'T have perma dom.
See the difference?
