More shadow war and arkfall type bosses only make them contested so they only spawn anywhere from 30 minutes to 2 days
Can you picture all the bug problems that would be created on top of the probs that are now in place now?
Personally, I'd love to see the Volge added in. Especially the Combat Walkers we see in the show. And possibly some more "Coldfire" weaponry like what is mentioned in-show; the way the Doc says it, I think most of the Votan weaponry(Sans Charge Blades, which is what Datak's knife/sword is actually called) are Coldfire weapons, yet in game, all the weapons act more like bullet weapons, not plasma weapons.
