How to nerf Fiddlesticks as a support
As you know, Fiddlesticks is pretty meta as a support now. He is very frustrating to face in lane, due to his E poke, and his Q which is an instant, undodgeable hard CC. And Fiddlesticks is one of the hardest poke supports to all-in in lane due to his point-click fear and his silence. W sustain also makes him resilient to poke.
Do you know why Fiddlesticks started to be dominant as a support? Well, a couple of patches ago, Riot made a change to his E which was meant to help him at jungle (which is intended to be his main role). They buffed the damage against monsters to 100%. However, there was also another change; they removed the bonus damage against minions.
V8.4 Dark Wind
Cooldown reduced to 10 seconds at all rank from 12 / 11.5 / 11 / 10.5 / 10. Bonus damage against monsters increased to 100% from 50%.**Removed: Dealing 50% bonus damage to minions. **
This change in particular was completely unecessary and only served to not only kill Middlesticks, which was a completely fine option and not dominant at all, but also make him OP as a support. Riot never stated the reason why they made this change in particular.
Why mid Fiddle needed this? Well, Dark Wind is already unreliable as a waveclear tool as it is. This was needed so that he could have some way to waveclear against many champions. He still got outpushed by dedicated waveclear champions. Despite dealing bonus damage against minions, Fiddlesticks' E didn't made him a waveclear monster like Taliyah or Galio are.
Why it made support Fiddle OP? Well, because Fiddle now has a significantly lower chance of stealing his ADC's farm. This has a couple of effects. The most obvious one is, now he can freely harass without the fear of acidentally last hitting a minion. This also allows him to make better use of
and
since those items have their gold generation paused if you last hit minions.
Another thing is that mid Fiddle can't afford to max Q second, since the damage from W (his drain) will be needed mid game if he actually wants to kill things, as mid Fiddle is expected to be the main magic damage source from the team. However, support Fiddle can freely max Q second, since he is the support after all. It doesn't matter that he is doing less damage, as long as he is having more utility. With that said, when he max Q second, it becomes noticeable how a 2,25 second point-click fear is cancer to play against (mid Fiddle would only have this at level 18, whereas support Fiddle will have it at level 13 max).
Lastly, mid Fiddle was way easier to counter in lane. A dedicated pushing champion like Taliyah, Azir, Aurelion Sol, or Malzahar, would make Fiddle struggle to do much, even if they couldn't directly fight Fiddle, they would just outpush him and outroam him. Fiddlesticks could be a soft counter to assassins and some burst mages, but even them assassins had a chance if they outpushed Fiddle. But for Fiddle support; If you don't all-in him with some tank support like Blitzcrank, he will just poke you down and win the lane, and unlike Brand, Fiddle's hard CC is point-click. Even Fiddle can somewhat deter all-ins thanks to this fear.
The ironic thing is that despite the fact that those changes were intended to help jungle Fiddle, this continues to be Fiddlesticks' worst role.
So how to solve the Fiddle issue?
Just revert the E changes! Make his E have 12 seconds at rank 1 again, reduced to 10 when maxed. And give it back the 50% bonus damage against minions. They don't even need to revert his E to 50% bonus damage against monsters.
This will not solve jungle Fiddle's issue, but will make sure that support Fiddle is a more balanced option, and will allow middle Fiddlesticks to be viable again.
