Yes, they do. I understand there is an acceptable way of doing it for lack of a better term. But I have also seem people sag and talk about how legit their stacks are. You kind of make it sound like every person that does everything does it the same way and that's simply not true.
Edit: I did notice in my original post I said "everyone does it now to achieve stacks". That probably created some of the confusion. I definitely didn't mean everyone in the literal sense. So my bad. I meant some people. Not everyone.
i feel you i still see people sag in MD
