It could have a slow or act as a dot, like Cassio's Miasma. Otherwise, the only wait to make this skill count for anything in teamfights is to combine it with CC - which, I guess, happens often enough, but when it doesn't the skill becomes useless. If it was changed this way, at least you'd get more than one tick of damage out of it.
