What if Fizz's Trickster...
Instead of making him invulnerable, caused him to take heavily reduced damage? I was talking about Fiora's Riposte with a friend, and he asked about Lissandra's ult being used on it. I mentioned it'd be negated entirely, but if it was Fizz, the timing could cause Lissandra to waste her cooldown, popping a large pillar of ice where Fizz would stand but doing zero damage to him, even allowhing him to ignore the aoe spread's damage.
I mean, Fizz's Trickster is pretty cancerous to League's health. Fizz typically rushes Hourglass after Lichbane/Runeglaive, and it just makes him incredibly frustrating but also frightening to deal with. Trickster > Hourglass > Trickster again. So what if instead, Trickster does...
50 / 60 / 70 / 80 / 90% reduced damage or 70 / 75 / 80 / 85 / 90% reduced damage
so that Fizz's enemies still have a moment to strike back and not waste long cooldowns oftentimes, while still making Fizz this deadly, slipperly, formidable assassin.
Thoughts?
