Serious and reasonable change to the "Troll pole"

Since Riot won't budge on the ability as a whole, and they won't change the damage... Could we make the hitbox much smaller? Say the size of fizz? Right now it seems excessively large, and it causes enough damage to make a dent in anyone it lands on. It's a very powerful dual purpose ability that could use a bit of counterplay against, and I think this might just be enough.
