[Suggestion] A game mechanic that will fix Kalista

**After playing Kalista a few times I realized that her weakness and the thing that can make her super op is her passive if you know how to use it you can be a god but if you don't you are gonna suck hard, after breaking my wrists playing her and trying to utilize her passive the best way I can I thought of something that can really help since her passive is so unique I don't think that changing it will be a good thing and I really think that if this change will be implemented she will be a bit easier to play. so I thought of making the shift + right click feature have a lock feature that way you can shift click and then normal right click away from your enemy to kite that way you also don't have to re aim your mouse every time you want to kite because you can either miss the champion you want to basic attack or you just end up clicking towards them and that can may get you killed and that way playing Kalista will be a lot less wrist breaking. as well I think that this feature will be great to focus down whoever you want in team fights not just on Kalista you can normally right click to attack whoever you want but if you have the champion you want to focus down locked you can shift right click and it will focus him. (If you understood what I mean you don't have to read this part I just explain it better over here) I realize that I may have explained the problem of playing Kalista poorly that well so I will try to explain it better: if you wanna utilize her passive you want to right click a champion and then right click the ground to walk to where you want to go (most of the times it's away from the champion since she is an amazing kiter) that makes playing her a lot harder since as I already mentioned you can miss your target every time you aim again at him or it might just be wrist breaking since it is very intense to play that champion, now a fix for it can be that you can shift click that way you attack the champion and walk to wherever you are pointing at BUT it only works for a 1v1 situation with no minions around because if there are more than one targets you can't control who the shift click is going to attack, so my fix as stated before is to add a lockdown feature to the shit right click so you can control who you are basic attacking with the shift click. ** Tell me what do you guys think and should it be a feature in League Of Legends?
