There really is no need to try to stop the HOing, just dodge it. Head-ons are part of every dogfight, and many times are what starts the fight. Yes there are people out there in the AH world who HO, run away and get some distance just to turn around to HO again, but that's where the "dodge the HO" comes in. No one ever said that if you are are going in head-on with an enemy that you HAVE to HO them. All you have to do is dodge them, don't try and HO. If you want then go ahead an do it, but if you don't want to HO or feel you won't win the Head-on then DON'T! Turn left or right at the right time, roll, split-s, do anything. There are more than one move to make when going in on a HO.
