And?
Alistar had a 90.2% P/B rate but a negative winrate in the LCK. And a 83.2% P/B rate in the LPL. Both stats just during the spring season.
Odd that i haven´t seen you complain about him. Far from me to think he's OP. He's balanced, really.
LPL Spring Season stats:
Lissandra: 55.3% P/B, with 61 games played, 64 games banned with a 59% WR.
Elise: 37.6% P/B, with 77 games played, 8 games banned with a 42.9% WR.
Twisted Fate: 28.8% P/B, with 18 games played, 47 games banned with a 72.2% WR.
LPL Summer Season stats:
Lissandra: 27.1% P/B, with 9 games played, 4 games banned with a 66.7% WR.
Elise: 25% P/B, with 10 games played, 2 games banned with a 20% WR.
Twisted Fate: 20.8% P/B, with 6 games played, 4 games banned with a 83.3% WR.
Overall, Lissandra had a good, rather balanced run in the LPL, despite being banned 3 games more.
Elise barely had any pressure at all. Both seasons of the LPL ended with her having negative Win Rates.
TF spent a lot of games banned on a ratio of nearly 3 banned games for every played game. But most of the games played, he won.
Does that mean he deserves a nerf? Hardly.
In more ways than one, he's an opposite case to Garen. In which Garen is good in normal ranked queue but bad in competitive, while TF is bad in ranked, good in competitive because of the utility he brings.
A nigh global ult that grants vision on enemies then allows him to teleport, gold card in hand, ready to gank? That´s extremely useful in competitive.
Now let´s move on to the LCK.
LCK Spring Season stats:
Lissandra: 64.2% P/B, with 70 games played, 68 games banned with a 48.6% WR.
Elise: 59.1% P/B, with 117 games played, 10 games banned with a 50.4% WR.
Twisted Fate: 38.6% P/B, with 27 games played, 56 games banned with a 66.7% WR.
LCK Summer Season stats:
Lissandra: Not played or banned.
Elise: 75.8% P/B, with 18 games played, 7 games banned with a 38.9% WR.
Twisted Fate: 30.3% P/B, with 2 games played, 8 games banned with a 50% WR.
In the LCK, Lissandra had a good run again, with an average winrate.
Elise only did fairly in the Spring season, falling to a below average and honestly poor winrate in the summer season.
TF still more banned than picked, but winning most games played. Still not indicative that he needs nerfs.
And the fact that Riot has not informed us of any changes to them, nor have done it on the first 3 PBE patches most likely mean they will not be receiving any at least for 6.17, and probably might have something in wait for them in the Worlds patch, but then again, most likely not since they are fairly balanced for what they do.
