I got an Imperial Ring doing the worm killing Assault mission a while back. I was aware that it worked in Salvage too, but surprised yesterday to see that it worked in the BLU+Soulflayer (42) and BLU+Alex (44) ToAU missions as well.
Is "Assault:" really just all instanced ToAU content? Or (perhaps glitched) all instanced Assault-style content including WotG stuff?
