So read the next patch and still no fiddle buff

Fiddlesticks' problem isn't the lack of a good jungle item. Some people didn't even bought Magus when it was avaliable.

Fiddlesticks' actual problems are the nerfs that he received BEFORE. For example... Changing the 3 second fear to a 2 second flee, making it so that enemies are only silenced once by Fiddlesticks' Dark Wind. Then, Riot made Dark Wind have priority on targets which have not been silenced yet, which made Fiddlesticks' harass way worse and made him much worse for solo lane/as a support. Lastly, we also have the nerfs to Drain's range, which made a lot easier for enemies to escape from his damage.

Also, Fiddlesticks' passive. That passive is not impactful outside of the early game or once your enemy buys a single magic resistance item. It feels so useless when compared to many other champion's passives.

Fiddlesticks is currently clunky to play and needs a rework.

120 mana cost on all spells

that's why he isn't viable
