Anyone know how Honor is calculated in AV?

[Kekkerer]

The honor system in AV is pretty simple:

1. Honor is gained for every tower/bunker destroyed and killing galv/baelinda.
2. Further honor is gained at the end of the AV for every tower/bunker defended on your side as well as galv/baelinda. You still get the bonus for the towers/bunkers when they are being captured but are not destroyed yet.
3. Daily BG and AV weekend bonus are added to the total.

Killing players of the opposing faction is not worth it if you're doing it for honor, it's really only good for HK achievements.
