Simple Champions With Too Much Power

Before Reading I would like to state that in no way do i expect any change nor am I asking for one, just curious as to what other players think of the situation in this discussion.

Ive just returned last month and have played a fair bit since returning after a year's break. And I have noticed something rather strange that occurred to me during a match.

There are some champions in this game that honestly don't belong as their simplistic and yet drastically powerful styles no longer stand alongside other champions cohesively. They completely outclass their opponents in a vast majority of cases and in late game, require a 5v1 to deal with. Ive had this situation occur with Xin Zhao every time I have seen that champion. Tryndamere is another instance of this. But its just one of those things that is able to be dealt with, but it just requires way more effort than should be necessary.

Im not saying they are way too powerful and need to be nerfed in this way and that, I am simply stating they do need some sort of attention whether its a rework or a change to the items they require. I feel as though simplicity shouldn't be so prevalent with hyper carries.

Below, post your views on their matter, any and all feedback is welcomed and will be read and responded to.
