LifeLine Idea

Hello everyone idk if a dev will see this but maybe the lifeline enjoyers or even someone who takes the time out of their day to read this will. I just wanna let it be known I do not play lifeline but I have played her before, I know many people that love her but can't play her due to the fact she's always not in a fast paced comp and she has no movement or there's just better options. Now for the idea/rework, with the addition of box respawns I think lifeline should be able to send doc to start a box respawn and when she does this the person that gets respawned comes back with half shield and full hp (full hp because doc respawned and well doc gives health to teammates) now I think it should be like a range thing that once in range of a deathbed you can press a button like R3 or F to send doc to respawn them... I haven't really thought about the idea of doc being destructible while being sent out or the cool downs. But I have thought of if you use this idea and respawn with doc you won't be able to immediately use doc again maybe half the cooldown of doc when you use him normally would be applied? Let me know what you guys think.
