RITO NEED CONTEXT ON THE FIDDLE PDE NERFS... I MEAN BUFFS
You want fiddle to be in the jungle. So you decide that nerfing him in the Lane and forcing him back into the jungle is the way to do it?
So lets look at the changes.
his "E" now th cd is now the same as the max level. (sweet buff but not to strong) cost 20 more mana per cast (wait a sec he is already a high mana cost champ. You removed mana regen. This is just a nerf to mid/support) deals 50% more damage to jungle mobs and 50% less to lane minions. (again nerfing mid but the "buff" to jungle isn't material.)
So at max rank this spell will now do 50% less to lane minion, 50% more to jungle but cost 20 mana more?
Lane fiddle has his farming nerfed hard (which is a major QoL for him that needs buffed), will run OOM faster now. So the lane opponent against the fiddle will he hit more often by "E" because of the lower CD and early levels. This is a change in QoL for the worst for Fiddle and the opponent.
Moving on to his ult. Right now all fiddle is, is his ult. Make it lower cd is just keep all his power in his ult. Power needs to be moved to other spots.
Jungle fiddle. So now i will save 4 secs on the recast.... but i only use it on Wolves and golems.... well that sucks. This is a very very very small buff in the jungle. But with the added mana cost and fiddle a heavy mana user it will just cause more people to counter jungle his blue and screw him early game. (before he can get the jungle item for mana)
Instead of crows bouncing of him, Fear cause jungle minions to take 30% more damage, after completing a drain / kill a drain target fiddle gains speed and plus ap or spell vamp, etc.. this is what you got?
Sure the change to the ult is a buff. However, when i want to ult. I'm more worried about can i ult in, will i instantly died, how to keep everyone on instantly using their mobility spells to get out, etc. This doesn't address any of these issues. And in the context of ult / cd his was way way too long to start with. Plus, i can play again when its up and not.
You take the things about fiddle that they mains hate (bad wave clear, no answer to mobility/cc, high mana cost) and make them worst. Then take what people playing again fiddle hate (ult, poke) and make it worst. The only class benefiting from this are ADC because support fiddle will take less farm.
Look we want QoL increase for both no decreases for both. Take all the changes back event the ult CD and try again. This will help no one.
