Kalista balance

We all know that Kalista use to be a really strong champion ( op ) and now with all these nerfs she feels unplayable practically, but what I found out ( adc main ) is that the main reason she is bad right now is probably the dash . Let me explain. Kalista is known for her incredible mobility BUT , when Kalista is slowed , her mobility drop drastically . I think that by fixing that bug on the passive so that u dash normally when slowed ( a full dash and the normal speed of the dash ) like with Lucian, when he is slowed it doesn't change the dash right! And it slows her attack speed too because her autos works with the passive but if u don't use it ( and that's her strength so...) Please riot consider this change for Kalista because I LOVE this champion and miss playing her like before !
