Is RIOT forgeting about champion pool in competitive play ?
These LC things are boring now with small pool champion. The pool size didnt change in last 3 years, when it was the show of 20 champions.
You can check the champion stats at here : http://lol.esportspedia.com/wiki/League_Championship_Series
If the champions isnt in top 20 champs, their pick/ban rate will below 30%. This state happened every years. The nerf/buff champ only replace some champion in pool, it didnt expand the pool.
Why riot cant face the fact that they still cant balance champions in LCK/LCS, even world championships ?
