Weaker or stronger is not the issue it is the xp range, you are gonna find lower levels who are strong and higher levels who are weak, and everything in between, but if you attack someone out of your xp range,( higher) they can retaliate for 24 hours , if that is what you are questioning the xp range fluctuates depending on your level ( xp range)
as far as guild wars, since I am not involved in that feature, this may help explain this was in the TGIF last night
A quick clarification about combat: Your Battle Range consists of everyone within 10% of your own level. This means that the more levels you have, the larger your range becomes and yes, it is possible for you to be in someone else's range, but not them in yours.
