what the heck is with this new update !! so many broken abilities !!

what were you guys thinking when making such broken stuff with this new update Riot !! Talon has no mana issues nor any cooldown issues having extensive mobility and massive shitty damage ! Rengar and Kha'zix are also just extremely powerful with just no limits to how strong they are even without inventory ! Ziggs abilities damage towers like they mean nothing to him ... just burst the shit out of it in seconds and his ability has more range than the tower itself to blow it ! kata, well I go no idea what's going on with her, the only way to bring her down was by hard CC when she moves in ... and now u can't even CC her and no cooldown when picks up her dagger when her passive is to remove cooldown on her abilities already !! zed's ability to steal damage from his "Death Mark" ... that's too much, he is an assassin... all he has to do is target the ADC, then even the opponent ADC would become weak even with inventories... ok its fine if he gets damage but if its permanent then it should have a downside... something like he loses his damage if he dies during "Death Mark" Illaoi heal is supposed to work only when she hits champions, there's a bug where in one of my match she had healed using it on minions... and the heal is way too much for a damn tank !! even Soraka's heal feels small compared to her... increase her cooldown or increase the mana cost on the abilities maybe...

I being an addict to LOL from more than 3 years now, with these new updates... Even I sometimes don't feel like playing with such unbalanced champions. Even beginners now can kick a veteran's ass with these unbalance.
