Hi!
In my opinion, this release was amazing! Rallying with others to prepare to fight knights feels awesome, so is the battle itself, the final instance, cutscenes and, of course, music – it is just epic. I would like to thank you, ANet, for bringing up this whole fight with such an epic melody!
If someone wants to hear the full ‘Battle on the Breachmaker’, it is on the ArenaNet’s official Soundcloud page or you can Google-Youtube it 
Once again, awesome epilogue overall! Cheers!
