Champion design from a players skill perspective. (Now and Then)

Wow, ok so, I just wrote like a 4 paragraphs talking about what I meant by this but for some reason my computer decided to hit the back key...

Alright so what I meant in the title is, generally the overall player base (or at least the pro's) have improved sense season 1 and before. Nowadays you see people Insecing others with in solo queue all the time. s outplaying whole teams, s tumbling their way to pentas, and s 1v5ing as far as the eye can see. Those sort of things didnt happen quite as much in season 1 and before. It's not all about the big plays though. You can look at CS scores. In season 4 any decent laner should have roughly 70 cs by 10 minutes. I don't have the exact numbers but im guessing that wasnt quite as high in the early launch/season 1.

TL;DR (Generally) Players are better now then in earlier seasons, how does this effect champ design.

Oh and also, this is the first post I have ever made on a forum. Sorry if this is in the wrong place.
