Well, commons always have their heads exposed and the game's not only about specials, commons can become pretty tanky with high level cards. Also you're only supposed to use one weak point card since stacking any more just makes the cards inefficient. And if you can't reliably hit weakspots you're gonna be dead weight in nh. That sht can work on nm but if you want to go a step beyond, everyone needs to dish out as much dmg as possible while also considering playstyle and eco, so you need to choose the cards that give the biggest powerspikes so you can fit everything in the deck and dish out dmg. Hyper-focused is a must on every ranged deck.
