The champion will become so good at high elo that riot will be forced to nerf the champion. This results in the champ being useless in low elo and average in high elo when mastered. This is why high skill champions dont work in LoL.
Ok and? If you don't like the champ don't play it.
There are 120+ others you can try out
If you can play it to the level of skill needed to thrive you make it up higher on the ladder. If at the Tippy Top its an outlier, it deserves to be nerfed. Same for if something has such a low floor its dominating the lower ends.
Balance outliers because its needed. Majority of the game should be for slightly above average level of skill when it comes to balancing decisions. This is just my opinion and I want to be clear on that.
