Sir_Shaggy's Wolf-on-Wolf Conquest, like a "Wolf Conquest s2", so everyone's a Wolf.
benoitremy74's proposal for a protect/capture, but if I could make an improvement, it would be that you have the same weapon selections as EX-Conquest for each team as an s2 selection, with names like "Fortress" and "Fortress s2".
codename09's Security Guard/Assassin idea, which is very similar to Ben's proposal above, but my changes to this would be the following: The NPC is not only wounded, but the protectors (Namely, the humans) have the ability carry him around like a bomb can be carried, but the person carrying him has the speed of when you're holding a turret (Really slow), can't use weapons, and has the appearance of carrying him in his arms. He can set him down by hold E and can pick him up the same way, like a bomb planting, and if the carrier dies, so does the NPC.
And my own proposal:
Merge the Conquest types into one single mode with extra selections, so Wolf Conquest (Named Wolf) and EX-Conquest (Named EX) would be available from the "s2" dropdown menu.
Also, I was going to suggest what Sir_Shaggy said, but he said it before me. ^^;
