Kalista 5.1 jump passive

When I played Kalista just now I was having trouble with her jump (yes, I did do very poorly in that match but it wasn't because the jump was changed). It feels like the time to proc the jump went way down. I know that they did something to the jump to make it so that you could change minion targets or something, but I just can't really get her to jump smoothly. Before I didn't have problems chaining the jumps. I don't think it's a bug because the jump still works it just seems like the window for the jump is way too small now. Anyone else have something on this?
