Hello,
 
	first of all, I have been ranking on retail vanilla and as well on several private vanilla servers and according to my knowledge and experience, when you do not pvp for a week,which practically means that you get less than 15 hks in that specific week, it means that you freeze and you are not considered as a person who did pvp, therefore you stay the same rank and % as you were.
 
	And basically what happened to me is that I played to lot for couple of weeks so I could achieve rank 10 alone. Once I got this rank, I felt like I need to take a break for a week or two and focus on another things like running dungeons, leveling professions and farming gold. And thats what I did last week, I did no pvp, I have 0 hks and 0 honor for last week, I did avoid all possible encounters and several times I even had to surrender to lvl 60 horde killing me to be sure I do not get any hks. And what happened is that I deranked to rank 9 and 50% even tho I have 0hks and 0 honor last week. So please, do you guys have any idea what might be the issue? Am I missing something here? 
 
	Thanks.
