State of characters
I think Fiddlesticks isn't working. It's not that his skills can't be clutch, or that he isn't ok, but with the current meta mobile champions are the biggest threat to everyone and having an ability that FORCES you to stand still to do damage (1 of his 2 "stable" damage abilities) means he is nerfed in a movement oriented meta. All it takes is one dash, stun or high attack speed and you explode. This is imbalanced. His e also only does one tick of damage on single target and it isn't high enough initially to meet the abilities of other casters. If you run away with the game, his ult is strong, yes, but is almost entirely reliant on the team being able to allow you to position, as well as on Zhonya's. Without it it is far less possible to even play the character. He should be rebuilt into a support with a similar skillset to this (or I would recommend being able to move and drain with less hp return, or maybe even make it a dot) while reducing overall bounce damage of his crows but increasing the initial hit to be more in line with other AP champions. His ult could implement a built in invinci (say he teleports to a position and becomes and untargetable scarecrow) but reduce the overall damage scaling due to the increased strength of the ability through it's mechanics. Something like that.
