You can't celebrate DOW if you only do it for one faction. DOW is DOW and not just the Imperium of Man. And I'm a Black Templars and Legion of the Damned fanatic, but I also like Khorne and his Berserkers. Here's hoping they'll soon announce DOW 3 since the DOW2 community and websites went back online few days ago, and I hope DOW3 plays more like DOW, with planetary conquests and all factions.
As Ratchet said, you never killed Revan in the Foundry. He simply used the Force and escaped to wherever. Would be kind of stupid if a group of 4 ~lvl38 whelps killed someone who's a master of both light and dark side.
