Twisted fate's gold card interraction with several champions !

Hi everyone. I'm playing on eune mostly but you get no support on eune or euw board so i'll stick to na board for a while ( forever ). I've posted bug reports there a lot of times but i feel like there is no rioters to maintain these boards. I'm bored of those boards, if i can call them so.

I've been playing twisted fate for a while now and i couldn't not realise how so many champions partially ignores it's gold card stun. There are way too many examples i can list here regarding it.

For example something i encountered yesterday -> Melee range vs renekton, i throw the gold card to him, he gets stunned, after 0.2s or so i wake up to him casting it's stun animation on me and therefore i get stunned. THIS i encountered too many times vs several champions where they'd cast things even while stunned. I just feel like twisted fate's stun does not act like others, lol. I've been playing udyr for 1 year or so and never ever encountered such things with his stun.

Take rek sai now ( this happened too many times), if you stun rek sai when he is about to enter its tunnel, even slighty before he entered, he'd still get all the way to the other side even stunned ( That usually means ignoring all the stun duration as if it was not even there since he is unable to cast any spell or move while he is in tunnel. He wouldn't care less if he had to still undergo the 0.2s left of the stun by the end of the tunnel. ) - hope you understand what i mean here.

THERE GOES THE NOTORIOSU SHACO THING, LOL ! I'm getting frustrated only when i think about this one. If you throw a card toward shaco and he ults, the card would just dissapear. But if you throw a damn not-on-target stun/spell he'd eat it all, right ? Then, if i throw a card to leblanc while her passive pops, she'd eat the stun, why shaco does not ?

I guess twisted fate players ( not casual players ), can relate to some of this as well. I'm waiting for some feedback, even some rioter's opinion on these listed.
