kalista update possibility

ADC's in league are kinda falling behind, Kalista is one of the worst (in my opinion, at least in low ELO ). i suggest turning her into a type of assassin ADC hybrid. first get rid of her hops, there kinda clunky and don't really add any real benefits. My idea for her is

 1) keep her rend stacks but change how they work. make them add % extra auto damage and give it a max stack of like 5 or 10. also give her a new passive of making her auto attacks go though targets losing range and damage based on how many units they go through, applying her rend stacks to all targets hit. this will give her good wave clear and poke for skilled players. Also make it so that the spears cant go passed her AA range and for every unit hit it will lose like 5% range. this could work in a way that if you want to get the full effect on a minion wave you'd have to be basically standing on top of the first minion to hit the last, so if you farm from afar you don't get the effect and this will make it so you actually have to be skilled to utilize it to the full extent and possibly put yourself in a bad position and get yourself killed if your not careful.

 2) give her some sort of mobility skill shot like she has now but increase the range of her jump so she can re-position her self in a fight, possibly give it stacks or maybe make it jump backwards like Caitlin's 50 cal net but with a knock bad that can maybe stun if the enemy hits a wall or other champion. this can help her get out of bad situations or chase if needed.

 3) another ability id like to see is some sort of channeled teleport at a short range. this can work with her current passive to bind with a champ (support) where she can possibly only port to the champ shes bonded to if he/she is in range, if you do that then make it a bigger range ( nothing crazy, something smaller than Ryze's ult) but something she can use to get into or out of fights, and make it like kindred's marks but she marks her allies and can only mark out of fights and has a decent CD. also to be able to play against the champ she binds to should have a mark visible to the enemy so they can asses whether or not they should stay and fight or turn and run.

4) her last ability could be something simple like an AOE field of spears that spike out of the ground at a decent range (maybe like Nautalis's E ability but instant. doing some damage and slowing enemies in range.  something simple to help kite or chase. it doesn't really even have to apply any stacks its more or less just an AOE slow.

5) finally change her ultimate. it makes her useless if her support or she roams. i think that her ultimate should be a big "global" spear. slow  moving and highly telegraphed like Ezreals but make it do more damage based on the number of rend stacks on what it hits. at max stacks it turns into an execute. it should do OK base damage and have a bit of AD scaling but its real power comes from hitting everyone with max rend stacks. this would generally be pretty hard to get off due to her having to be positioned where everyone gets hit and gets stacked and the highly telegraphed channel to do the ult but if you can it can be devastating in a team fight if you can pull it off.

With all of these changes to her she would basically be a completely new champ but i think it could expand her play style and make her a relevant champion again that doesn't completely rely on her support to do anything. i also think she can do more than just ADC but other roles can be filled like mid top or Jung. she would be highly mobile with tons of damage but at the same time with more skill shots and telegraphed abilities it would still be fair to play against her i think this would be a great balance to make her way more fun and make the role of ADC fun again.
