She's getting nerfed, albeit not with proposed changes I'm sure will actually affect her much from what was being proposed. The problem with Caitlyn right now is, she's an effective lane bully due to her range, and it affords her too much leeway in getting past her notorious mid-game slump. Her traps serve a dual purpose of enabling aggression for herself, while negating aggression for her opponents, with very limited counterplay involved. Her net lets her reposition quickly when needed, and Piltover Peacemaker gives her wave-clearing power.
It sounds really stupidly strong now, but in the past, it's where she had to be in order to stay relevant. Over time though, things have just shifted to give her a lot of power, with her peers getting nerfed, attack speed/crit itemization being buffed basically across the board, and the meta being focused around lane control for early drakes, deep vision in the enemy jungle, etc.
She's not OMG UNBEARABLE but it's fair that they're looking to trim down her strength a bit, after the last few patches have really boosted her.
