Kalista Is Unplayable

This is the first time I've posted on these forums. I feel compelled to let everyone know that one of my favorite champions has seriously something wrong with her. For anyone that doesn't know, Kalista was undeservingly nerfed earlier this year. They lowered her base attack speed into the ground and gave her W a passive that gives her only a fraction of that attack speed back when she's nearby her support. Riot also nerfed her damage, and worked it into a passive that when the support and adc attack the same target it deals % damage, but only procs every ten seconds or so.

I find it nearly impossible to win with this champion now, compared to before, when I was getting Pentakills. She's like a slower, weaker Kogmaw . I found a build path that somewhat makes her viable, but is only obtainable by heavy farming and lucky kills. The only way that I can even remotely keep my head above water is to buy Cull and farm until late game. After Cull I go then then . Assuming the other adc has no kills and has been farming, this puts me on equal ground (capable of killing other champs). This build is usually finished at the 30min mark and at that point, it's usually too late because the other lanes are destroyed or well-fed.

I played nine games today with Kalista and I lost them all, but one. I've been playing Kalista off and on because she's fun, but I almost always lose.

Please, Riot. Just give her a little something to make life easier.
