We. Have. A. Cannon.
So, remember in Siege of Orgrimmar how we blow up the cannons by the shoreline right befor Galakras? Here, we kill a bunch of trash and then capture cannons.
And use them.
It's almost like we've learned something! And by we, I mean the Alliance leadership. Because we pointed it out to them every single time we did Galakras, and did they listen then? No. No they did not.
Where was I? Oh yes. We have cannons. And we use them to blow a hole in the door to Hellfire Citadel.
Many waves of adds, of which the berserkers hit the hardest, and we avoid bombs and stuff. And destroyer siege weapons to protect our cannons. And feed our cannons with what the siege weapons leave behind.
Something a little bit different. :)
