Nostalrius Begins - Quality wow vanilla realm (1.12)

Today's update didn't credit me with the correct honor and HK.

I also noticed that today when i played earlier and killed 4 people all of them were the same lvl as me or maybe 1 lower/higher and i didn't get credit for any of those kills.

Do you have anything for them to reference your claims on?
Before and after pictures?

Honor is your Honor Tab is your estimated honor, not actual honor earned. There are a lot of factors that go into play, such as diminishing returns that effect your final honor count. These aren't factored into your estimated honor, so sometimes you can end up getting more or less than what your estimated honor says on the tab.

The players you killed earlier, had you already killed them over 5 times recently? If so that's the diminishing returns. Did another player or group kill the players, and you just sorta were there? If so honor is calculated based on how much damage/healing you do during the fight. If you hit them once and did next to zero damage, you would get zero honor.
