shroud - leviathan listens to shroud

It's becoming increasingly common to go into an unrated lobby and have someone complaining about how bad their team mates are. I usually play unrated with my friends who have big rank disparity and my lower ranking friends always get abuse...

Playing as Omen, you can see your smokes fly towards the targeted location as a little blob before turning into a smoke on the map. Can enemies also see this blob (and give away the general location of the enemy Omen)?
