so basically, you just said that there is no problem, only that instead there are not enough assassins in mid lane?
most of them already feel terrible to play against and they've used most of the conventional means of killing someone already. Pyke is the first assassin added in a while and what they ended up getting wrong about him was a mistake that had been made previously: free gold . Then you add to that a large amount of sustain...
assassins aren't troll picks anywhere outside of professional play...
Zed, leblanc, kassadin, akali, katarina, ekko, talon,
their pick rates come to 50.6% total worldwide
you literally see an assassin in half of games...the numbers show an interesting change as well
Assassin numbers go down in the US(only to 47.3%, but their win-rates start to get very high
1/9 diamond matches involves zed, zed has a 54% win rate and 30% ban rate
Fizz at 6% pick rate(above average pick rate of 3%) has a 54% win rate
Kassadin and Leblanc have been put through the ringer more than a few times and there are probably some external factors (like jungler and top picks) influencing them, 7.9 and 7.5 pick rates with 48.8% and 47.8% win rates currently
katarina 5.2% pick and 51.6% win (basically above average in both ways)
ekko 5.7 and 52%
akali is still recovering from riot's "problems" with balancing at 5.1% and 43%
Here's a fun one though, I wonder what has spiked Taliya's winrate up to 57% at 3% pick rate (average pick rate, extreme win rate for average )
