90% this dude invaded and is complaining about a host not wanting to die. Healing is fair game in invasions. Save your honor for the arenas or RSS, those of you looking to get into the series for the remaster.
Lemme tell you something here sparky, if the unmodified game mechanics allow it, I'm going to do/use it. Save your sniveling crybaby complaints for the devs who are rightfully going to laugh at you.
Get good and go hard or go home.
