yeah fiddlesticks is... just not very strong
lot of people don't understand why... it took me years to understand what is wrong with fiddle !!!
Basicaly, sometimes he can "feel" strong... but he has so many flaws that makes him unplayable/frustrating
scenario 1: you think you are doing a good game, you are 5/0/5... you kill 3 of them but ennemy jungler lives, your team insist to do baron (surely ennemy jungler cannot steal it taht easily)
but fiddlesticks get outsmited everytime because (you are underleveled / you cannot combo with another spell to smite)
scenario 2: game get in late game, you are 15/2/20... you are useless as fuck ! yeah they bought adaptative helm and your E cannot bounce !!!
scenario 3: you and your team are doing great since minute 1... but a bad fight and you die !
you hope your team will def baron !!! they fight ! you respawn and you want to def baron !!! but NO ! you don't have ult ! you are useless as fuck ^^
scenario 4: an ennemy in the ennemy team do you the honor of countering you... he doesn't pick janna, he picks something that can put wards and even cancel your ult...
scenario 5: you thought you can kill a 0/5 blitzcrank with you 10/0 fiddle ? actually no... you probably cannot ! if you meet him in 1v1 you are probably dead as fuck
scenario 6: an ennemy have 5% hp, but there is no creep around him... can you kill him ? no. E does NO damage if it doesn't bounce
scenario 7: you lose your first blue... if you play in elo higher than gold you can almost already ff since you cannot farm anymore
other problems: cannot really start red... so easy to counter ^^
