that would work, but these groups aren't going for the honor, but the HK's. I suppose they could make it so people do not afford a honourable kill when slain this way, but how would that interact with say, reinforcement values?Surely, a "recently slain" debuff would fix this (much like the debuff of the same name that is applied in Wintergrasp): each time you are killed, you aren't worth any honor points to that enemy for a short duration, stacking if killed within that duration.
Seeing as graveyard camping (probably) has negative feedback for all those involved (because of the 40-man HK premades at least), we could see the end of graveyard camping in whatever change they are going to roll out over this issue.
