Riot, If Irelias winrate is wierd when she is released..
Just realize you shouldnt buff/nerf her
If her WR is 52%+ dont nerf her . The reason is simply because finding counterplay takes a while, and until a week or two passes, thats when you should hit the nerfs (NOT LARGE SCALE THO)
Same with 48% and below. People dont know how to use her, so dont give her buffs like you did kai'sa, yes the kai buffs were needed, but were they overly exaggerated? yes. dont do this to irelia, she seems really good, and she will be a yasuo champ, so you know that she will have a high play rate (meaning many bad players will make her WR go down) and not to mention how hard she looks to master.
just leave Irelia in her rework base form for now. Wait 2-4 weeks before turning her into super saiyan 3 or either turning her into the newest, latest version of the trash can 3000
