PSA: Be considerate of your teammates and don't play Kayle or Morgana in ranked if you're first time
Yes, they have cool splashes and they are very fresh and shiny, but for the love of God, don't play them just because you got bought a skin after their reworks. It's simply disrespectful, there are plenty of other game modes to practice them in, and you're jeopardizing the time, fun and LP of four other people.
It's especially stressful when you see someone hovering Kayle or Morgana, and you see the person has zero past games with them on their op.gg. You don't know if you'd rather have them feed on those champs, or if you'd rather ban the champ and have them tilt/feed anyways.
