Even if you consider mana and cd's, it would still be possible for Teemo to place several shrooms in one place to stack them to make a pseudo-nuke, especially in the top lane brush (not the one in the river), buffs, or baron/dragon. He can still keep vision of key objectives while having even higher damage than before.
