The reason she has consistently received nerfs is because of how extremely reliable caitlyn is just as a champion. she has one of the the easiest early games with her larger than average attack range, she can siege or defend quite well with trap lines, and her late game is godlike. However, she was very simple to the point of just right clicking to win a team fight with runnans. Even now, without runnans, with a few attack speed items she can stack headshots pretty quickly, and they still hurt. She is still receiving bans in the LCS. As a level 7 Caitlyn player, i can definitely feel the changes she has consistently received. However, now, without her runnans headshot mechanics, she becomes a lot more focused on using traps to her advantage. I would say she takes a lot more skill now that I don't just right click and kill everyone late game. Trust me you can still carry hard with caitlyn, it just takes a little more skill to make the most out her now.
