"braindead fuck" -- i've been in the pure scene a lot longer than you, senior member of mayhem makers with 2 clan cups under my belt and I still am active in the pure scene.
everyone pks with 75 atk 13 pray bh worlds. risk fighting with gmaul insta -> bgs. NHing is shit on that account with it's current stats. 75 atk isn't worth it until you max out or actively do clan wars minis with clans.
Compare that to my level 75s, let me know what is good for nhing (which is all i do):

I'm not bagging on 75 atk pures, I'm just saying that one is pointless because at 75 atk you should be 13 prayer to risk fight, or maxed before you step foot deep wild to nh. You'll get slapped around until you max out. (I even have a 75 atker:
