A single, simple change, that would make Fiddle a better champion.
I love Fiddle, as support, mid or jungle. I can see why he is left at such a week state currently - he has a long fear and a very strong ult. Yet still, people don't play him. Sometimes he is even considered a troll pick.. Why would i pick fiddle to jungle with, when i can get Graves, Heca, Zac ( and almost any other ad jungler ). He is such a niche pick, which can only work in certain rare scenarios and vs certain champs ! But seeing how every new champ has some form of dash/flash/escape mechanism, it is an easy escape from the ult, unless Fiddle burns a summoner or waits for the right moment - which in SoloQ almost never comes. He is ultra strong game changer if he manages to catch all 5 ( or at least 4 )people in it AND make them stay in it - which is the tricky part. Without his ult he is extremely weak. Has a very hard time pre-6, free counter jungle, such hard ganks etc. He is not mobile. He has hard time dueling people and remaining relevant.
I suggest a single, simple change, which I believe would buff him, without OPing him, making him more viable. His W outside of his ult, is what makes Fiddle- Fiddle. Yet it feels so hard to play with it outside of clearing jungle camps. Go to fight someone press W and most of the times they will run away OR just kill you while channelling it. Why not make his W like a tether ability. Allowing him to move while channelling it ? I believe this small change would make his life so much easier without making him overbearing. Considering that if he uses Q or E, the channelling would stop anyways.. Everything in his kit requires certain things to happen - for example, you need 2 people to be close together to make full use of his E, otherwise it would hit them only once - which is like hitting them with cotton. His Q is also a bit random, because you cannot control which way the enemy would flee - so many times i press Q, yet they 'flee' on top of me, so I can't escape or fight back again. His ult i already explained is hard to pull off, his W is even harder, because the range is so small, the damage is not fast enough to do its job, so people simply walk out of it, then resume to kill you while it is on CD - fiddle's CD is also pretty high.
So yes, apart from total rework, I truly believe such a change would make him a bit more viable. Also I don't believe in changing numbers.. in my eyes it is never a good way to nerf or buff someone.
So TL:DR - I suggest allowing you to move while channelling W, only way to stop it is to press W again or use another ability. This way he will be more viable at 1v1 and ganking ( outside of ult ganks, which still is hard to pull off ). Thank you all for reading !
