As of the time I write this, the Hangar is, in my eyes, the most important of the siege production nodes. This stems from two reasons.

 

One: you can't attack the airship. Where as with the Docks or Workshop, which create vehicles you drive up into the fight, the airship flies on a predetermined course high, high in the sky. While players can use the keep's turrets or go out on foot to destroy approaching vehicles, the airship is too far away to be attacked by players or turrets.

 

Two: It allows you to paradrop massive amounts of troops into the enemy base. It's interesting to note that while the keep does have turrets, none of them can shoot inside the courtyard. The only threat to paradropping players are other, enemy players. While you'd think the enemy players would have the home field advantage (they respawn there, after all,) that's not the case. The airship can quite effectively lay down suppressive fire that will quickly injure or kill anyone who gets hit.

 

At first glance, you would think it'd be more effective to bring up a massive machine of war than to just drop in and plant bombs. The reason paradropping is so effective, though, is that there is no limit to how many people can drop inside and plant bombs. You are limited on the other machines, however; two catapults, two glaive throwers, and four demolishers at one time.

 

Twenty people armed with Huge Seaforium Bombs, assisted by the five player controlled cannons from the airship, can very quickly do a lot of damage to a gate.

Just wanted to compare this to something that I'v seen abit in my battlegroup (Cyclone) and see what other players think. Even with the above strategy which seems to me like a premade strategy (need a well groomed and synergized group to actually stay in there base for awhile, or at least competent players) the enemy faction seems able to balance it out and come out on top by using the Oil Refinery and Quarry's buffs to there advantage.

You've got probably 35 or so players inside a base using C4 on the gate, for 6k or so each blast. But for the other side, grabing the other nodes and for a total of 30% increased seige damage //www.wowhead.com/?spell=68719, several heavy seige tanks and there own players using catapaults to gain access to C4 themselves, wouldn't the team controling all the nodes have a much higher damage on the door and a higher chance of winning?

Thats what it seems like to me, and it worries me that the more players see this strategy and try it in a highly uncoordinated or fully pugged BG, the higher chance of it not working. Your thoughts? And I do play Horde, so there are quite abit of uncoordinated battlegrounds -.-
