I know what you are talking about, these days:
Why are alliance still allowed to make a full premade in AV? - WoW Classic / WoW Classic General Discussion - World of Warcraft Forums (blizzard.com)
Any horde that stuck through those games and made the best of them I’ve got to respect.
0 honor games for the horde and max honor games for the alliance were the goal of the alliance (most of whom weren’t there for the honor, but for revenge as the allies got farmed for a year in that BG) and were common.
As for the “map imbalance” there isn’t one. Burning bunkers fully and sending back wing commanders counts for honor. Once a bunker gets taken back by the alliance (which happens almost all the time) that’s another 198 for them. Whereas we put no focus on taking back our towers so we lost 198 each.
One group of 5 taking back the horde towers would give the horde more honor but the current AV people don’t understand this.
