Kalista Suggestion
Hey, I really love Kalista's overall design, but with all this dislike to her kit I figured I'd add my own suggestion! To fit her lore as the vengeance seeker and to give more use to the spear I've come up with a change to her passive and Q. First I think moving her Martial Poise passive to only proc off her Q would add a lot of fairness, but as a new passive, being the Vengeance seeker and all she could have this. Passive: Betrayal's Lament Upon the death of the Soul-Bound will become etheral and cannot be targeted by the enemy team. During this time the Soul-Bound champion that is dead may attack, target, or affect only the champion responsible for their death. If champions assisted they may be targeted too. This effect lasts for up to 5/7/9 seconds or until Kalista and the Soul-Bound are out of range of each other. Kalista's ult can still be used during this time, but it will only hit the champions that the Soul-Bound may target.
I think this new passive would work with her lore a lot more and also allow for a passive that can help a team that is falling behind. While it does require a death to proc, this passive has a load of different ways it can work. With the champion that dies being immune to everything they are able to exact revenge, but at the same time when Kalista is killed she's considered out of range. Since Kalista is still mainly played as ADC this would allow her to have her support help a little more, but at the same time support champions such as Soraka won't be able to do much with the heals and shields can't be used. You're only able to target the person that killed you which also means if a jungler comes to the fight after your death he cannot be targeted. She'll also still have her mobility and chance to jump over walls with her Q, but it will be much less often and give Melee champions such as Darius or Garen a fighting chance.
