Fiddle in the jungle is too weak
According to op.gg , he's currently sitting at a 47% winrate - that's pretty weak, he needs a buff to be viable. 47% winrate means that if you play 1 game per day, on average in a month you'll lose 1 more game with him than with anoth... Wait, 1 more loss per MONTH???

WHO THE HELL CARES! I'm not playing in the LCS, that 3% winrate from 50% means LESS THAN NOTHING anywhere that is not high-level competitive!

Is he weak in League-Of-One-Shots? Yeah, maybe. But you know what? There are other ways to contribute. Maybe I won't be able to assassinate other people, but if you eat a 5-man ult my Yi is going to get a pentakill. Maybe I won't be able to duel the enemy jungler, but he better keep tabs on me or I'll get every single dragon from level 5 onward. Maybe I won't be able to delete the enemy ADC like the enemy Zed would, but I can still make that Zed miserable if he tries while my ult is down.
TL;DR Play what you like, and don't mind winrates and viability - they're a minor nuisance at worst if you're not a pro.
