Kalista should get a bonus when her soulbound dies

Or... just bear with me here. Kalista gets a bonus ability when her support baits her into a fight she knows they can't win. It's called "betrayed". When she is betrayed by her support in such a terrible manner the range of her ult is increased and the soulbounds controls are removed. She can then willingly catapult her support from anywhere on the map to the enemy spawn where they will be brutally murdered by the spawn turret.

Why do we want to buff Kalista? Also that just means Kalista will always sacrifice their support for double kills.

Sorry but I don't want to tower dive every time Kalista wants a small buff...

I'd prefer a simple "within 2 seconds you can teleport to their dead body" in order to take revenge. Fits the theme and doesn't increase power or anything, just makes you think twice about diving the soulbound. Could also be forced, but that may not work too well. I understand the premise though.
