Winning AV, as alliance:
From the start gate, make a beeline for Captain Galvangar, with 1 or 2 breaking off to take Snowfall Graveyard, and a stealth class to grab Irondeep Mines. Engage and kill Captain Galvanagar, then head on to cap Iceblood Graveyard, Iceblood Tower and Tower Point. If there are lots of Horde in Galvanagar's room, take Iceblood Graveyard, Iceblood Tower and Tower first. Then, try to lure out and kill the Horde players individually. If you pull Galvangar, run out to reset him unless there are only a few Horde players left. Once the Horde numbers have dwindled to around 5, you can engage Galvangar.
Once Galvangar is dead, proceed on south towards the Frostwolf Base. Leave between 5-8 people each in Iceblood Tower and Tower Point and 3-5 at Iceblood Graveyard to prevent backcaps, and atleast a group of 5-10 to head back north to backcap Stonehearth Graveyard, then Stonehearth Bunker and Icewing Bunker. If the backcap group is quick and strong enough, they should consider backcapping Stormpike Graveyard, and even North and South Dun Baldar Bunkers.
Those not on backcapping or tower/graveyard holding duty should proceed directly to the Frostwolf Base, with the exception of one stealth class player going in to take Coldtooth Mine. Horde are easier to avoid/deal with they respawn at Frostwolf Graveyard than they respawn at Frostwolf Relief Hut, so avoid taking Frostwolf Graveyard until Frostwolf Relief Hut is taken. The only time Frostwolf Graveyard would be taken first is if Horde have a large force assembled outside the room with their General, Drek'Thar. Once inside the base, have a few people cap Frostwolf relief hut while the rest of the players help take East and West Frostwolf Towers.
When Iceblood Graveyard is owned by the Alliance, Iceblood Tower and/or Tower Point is destroyed, the people defending those nodes should move to 1 of the other 2 node until all 3 have been captured/destroyed. From there, they help retake whatever node the Horde has backcapped. If no node was backcapped (ignore Snowfall Graveyard for now), have the option of either helping backcap or helping with offense in the Frostwolf base. Usually, it's better for the players to head towards Frostwolf Base.
Once Frostwolf towers are capped and waiting to be destroyed, the next thing is to decide when to attack the Frost Wolf General, Drek'Thar. Drek'Thar has two wolf adds and a Warmaster add for each tower that has not been destroyed. Each Warmaster still up increases the health and damage of each Frostwolf NPC in Drek'Thar's room, including Drek'Thar himself. So the best situation to attack Drek'Thar would be when all 4 towers are destroyed, but such a situation does not occur. Depending on when towers and bunkers were capped/backcapped, the Horde may have all the bunkers destroyed before you have all the towers destroyed, which in that case, you have to engage Drek'Thar with warmasters still up.
When you engage Drek'Thar, pop cooldowns to down him as fast as possible, and dps should be on the alert for any Horde who sneak in and try to CC/Kill your healers or your tank. The last thing you want, especially with warmasters up, is a Horde druid cycloning your tank, or a Horde Rogue stunning/smokebombing your tank, as that could lead to you wiping on Drek'Thar. If you get aggro from Drek'Thar, do not leave the room, or you could end up reset Drek'Thar back to full health. It's best that you die in his room than to run out and reset him. Also, have a few dps at the entrance to Drek'Thar's room to catch any Horde trying to sneak in.
Finally, some pointers when deciding the best time to engage Drek'Thar:
-- You can engage him when all the towers are destroyed if by the time the last tower is destroyed you will still have 3-4 bunkers still up.
-- Drek'Thar is doable with 2 Warmasters up. Engage him with 2 towers still up only if the Horde will be able to have destroyed at least 3 of your bunkers before you destroy the 3rd tower.
-- In a situation that is reversed from the one described above, be ready to engage when the Horde pull Vaan. You can hold off and wait for a tower to be destroyed if the tower will be destroyed no more than 30 seconds after the Horde engage Vaan.
