Poor Fiddlesticks... How much longer he will be left on that state?
Fiddlesticks received some nerfs during last year, that weakened his power and viability in lanes. First, they nerfed his fear, making it last for less seconds and become a "flee" instead, this (thogether with the nerfs to Spellthief's Edge) made Fiddlesticks weaker as a support, and thus, people stopped using him on that lane.
The above nerf also made Fiddlesticks weaker on mid lane, where he was previously viable, but the nail on the coffin was the nerfs that were to be introduced later. His silence not only prioritize enemies that have not yet been hit, but it also only silences on the first hit. This made his harass very weak and killed his viability as a mid laner, he already wasn't the best of mid laners, but now there is no reason to use him when there is Vladimir, which has the same level of sustain as Fiddlesticks, but is much more suitable for laning, and the only advantage that Fiddlesticks has over Vlad is CC.
The last place in which Fiddlesticks could still possibly be viable was the jungle, although Fiddlesticks has problems with early game champions that could invade his jungle, also Fiddlesticks has slow jungle clear, and the Magus enchantment was lacking in mana regeneration or restoration. However, ever since Riot replaced Magus with Runeglaive, this has hurt Fiddlesticks a lot, he is now a very weak jungler too, as Runeglaive is a very innefective enchantment for him and there is no other enchantment that is good for Fiddlesticks.
Now the only place where on my opinion Fiddlesticks is still possibly viable is a support, but even then, why should I pick Fiddlesticks, when I can pick Lulu, who also has harass and a reliable CC, but has much more utility? The only possible reason to pick Fiddlesticks over Lulu, is if the rest of your team is full AD and you need a support who can sacrifice some of its utility items to build AP and help its team in doing magic damage, but supports shouldn't be usually building for damage.
Fiddlesticks is now very weak and is outclassed by so many champions. He still has an amazing late game, he is very strong at late, with fantastic teamfighting presence, strong AoE damage, and reliable CC. The problem is that he now has an extremely hard time reaching said late game. And even then I can pick other champions that have a good late game but can do some of the same things that Fiddlesticks can do.
Mage that can do massive AoE damage late game? Karthus, Vladimir, Ezreal, Anivia, Vel'Koz, Ziggs, Kennen.
Mage that has reliable sustain? Vladimir, Swain, Morgana, Ahri, Nidalee.
Mage that has reliable, targeted CC? Annie, Ryze, Twisted Fate, Lissandra, Malzahar.
I hope that Riot is planning some sort of buffs, or even a rework for Fiddlesticks, as of now he has a lot of problems, I know that he isn't an easy problem to address, but still, I want to play one of my old favorite champion again.
Edit: His problems are not only gameplay and balance-wise, lore-wise he also has some problems, for example, now that there are no "League of Legends" (the League itself) anymore, from which place Fiddlesticks has came? This has no explanation. Also, he doesn't make any sense as a Zaun champion.
Also, his voice over is terrible. Tahm Kench has much more attacking quotes than Fiddlesticks has quotes on his entire VO.
