unpopular opinion: the fizz nerf goes into the entirely wrong direction.
this is the same nerf you gave fioras riposte and the wrong type of nerf. it nerfs a squishy assassin fizz more than a bruiser fizz, since its taking away from the mechanic that allows him to be squishy while diving onto the enemy in the first place.
this nerfs assassin fizz and forces him into a bruiser build to compensate for the reduced innate defense, while making him less effective on that build.
his troll pole needs changes, because the ability is simply overloaded as a double gap closer, dodge mechanic and burst damage ability. but this is not it.
what he needs right now first and foremost is ap scalings added in certain places where he doesnt have them. mainly his % missing health damage scale on ability power, so he doesnt deal a load of item independent damage without building ap.
change it to deal x% missing health damage per 100 ap instead of just dealing x% missing health damage per rank of the ability.
this should make him a lot less effective when hes stacking defense instead of building ap.
