I stopped complaining about Kalista when I tried to play her vs Bots and 1 PvP normal Game when she was on a free week. Idk, she's maybe not my style bit she's really hard to play imo. I have to admit that when you get killed by Kalista it looks like you have just got outplayed due to her passive and the way it looks like when she jumps but no. Actually I whink she is kinda weak early since she's rushing pure AS at early stages so she isn't that good at killing towers and trading with caster ADCs such are Lucian, Graves and Tristana.
Do not get me wrong, I am not playing her and I do not have her in my champion pool so I am not protecting her. I agree its kinda frustrating to play against Kalista...even a bad one can look like she's pro but meh....Jinx is much more of a problem imo since she counts as a Hyper Late Game Carry while still having much better early game than Draven, Kog, Twitch, Tristana and Vayne for example. And Jinx could be toned down without being gutted, Just damn remove the crit chance from her rockets and she would be one of the healthiest ADCs in game sitting next to Caitlyn and Sivir :)
