My post from another thread

"Nono not exactly, AV is sucky for Horde here too . It's just that having a multiboxer can really imo change things. Most of my friends just don't do any AVs at all because it really sucks (solo) and they have almost the opposite %.

I've done hundreds and hundreds of AVs, people start knowing me and playing it as I stated in my post. That helps a lot, a multiboxer cannot win alone oc . If you manage to keep those 5-8 around you in defense you win most of the time.
Even when it turns out really bad I cannot even count how many AVs I've won after losing all towers and defending our king with a few more people.

That strategy, defend Galva for a while (very important: defend like once and then just go to towers, leave it alone for them to kill), recover towers, kill anyone going south, defend southern graveyards and above all motivating those few players to stay with you all it does in fact is giving Horde time to "breathe". The terrain favors alliance so the strategy is gain time so our guys can go north, cap a couple of towers and kill the king.
If you see that alliance isn't moving fast as they usually do, you can move north and cap one DB tower (I'm able to cap it almost all the time as they don't get organized to defend it..., sometimes I even cap both).
Vanndar is killable with two marshalls up even without a tank. Just tell a healer to spam heal on ONE of your elementals, pop all 4. That, along with some more dpsers around (not many needed) and your huge burst drops their king in no time.

I never ever attack as a main strategy. People (other players) appreciate that, see that I play the game and are then willingly helping me defending."
