Nerf Kalista please, so the game can be playable

How to start -endlessly stacking spears that function as a smite, execute, and primary damage source that can be applied to multiple targets -this damage source refund's it's mana cost after landing on two targets, making farming literally nothing -a dash, next to knock ups the best ability in the game, is assigned to every auto attack, and due to the recent changes, Kalista can now get auto's out while stunned due to animation timing -the best "get out of jail free card" in the entire game in the form of her ult, allowing for her "soulmate" to royally screw up and get out with basically negative hp with only the cost of a very short cool down

• an ability that allows her to use her dash apart from her aggression to dodge and still do damage so long as it kills a minion -vision control for essentially free, as 90% of her damage refunds it's self in mana after landing on two targets -ROFL stomps basically any squishy or skill-shot dependent carry, only really shut down by graves, and even then if she is given 5 free autos early he is now at half health
• Did I mention rend is op? as it has no cool down and also slows
• Her only weakness is point-click cc, which is hard to come by as most of the true hardcore point and click lockdown abilities were deemed "op" and therefore nerfed, allowing kali basically free rein so long as the enemy team doesn't have a Vi, and even then with even okay mechanics, if the vi is not full damage and just one shots her, she can kite away with no consequence What would you say if I told you twitch now had a dash on every auto, indefinitely stacking poison, and his contaminate now regens its' mana cost if you poison multiple targets? Knowing the league community, you would probably tell me to kill myself, and that's what I want to do when I see an enemy Kalista

Tl;dr Kalista literally ruins the game, and I don't care if she is fun to watch competitively, I want her fixed.
