Most fun champion that you suck at?
Mine has got to be
. I'm terribad at ADC in general but damn is Kalista fun. With her short range, you absolutely have to rely on kiting and being 1 inch away from death all the time, but it feels so nice to use Rend for a nice execute. I don't know why, but as Kalista, I feel I can actually do something in teamfights, whereas with other short ranged kiting ADCs I have no idea what I'm doing in teamfights and just feed.
She's also mechanically quite intensive but intuitive.

and 




Just can't seem to rek people with Rek'sai.
I like the idea if being invisible, but I never do well with him... I either, never get my combo right or ult in at the wrong time.
Honestly. I love his kit and everything about it. Its a beautiful design. I've played against decent Twisted Fates before but I cannot do well with the champion for some odd reason. Feed every game, whether I'm farming or playing aggressive, roaming, or sitting under tower. Just don't get it lol. (had the great fortune to queue as Ahri against a Diamond 4 TF in normals a few months ago. Superior game sense and mechanics>mobility. Every time)
i can't take any games seriously when i play him. spend too much time spamming taunt and ulting in random places just to see if i can hit anything.
i suck laning phase with him but am godly in tfs which is exact opposite of what i should be xD
