Wasnt able to find this elsewhere, so im sorry if its a repost.
I was running around WG today, when i noticed that the hordes tenacity buff went 1 up every time i mounted my mechano-hog. The buff works in that way that the more ratio-advantage the opposing faction have, the more buffs you get.. So with 30 alliances, and 20 hordes, the horde would have 10 tenacity stacks.
For not just telling people to not mount their vehicles when in WG, for a better chance of winning, then it's gotta be a bug. Maybe count as a player in outdoor-instances etc.
Anyways, hopefully it's gonna be useful for someone sometime.
