TAHM KENCH MECHANIC IDEA. PLEASE READ.

Hello, i just thought, hey, it would probably suck to be the person inside tahm kench while hes getting wailed on by the enemy team. so heres my thought, for a more strategic use in team fights, other than just deleting someone from the map. introduce "turbulence" where, any ally inside of tahm kench, also takes 10% of the % HP tahm kench loses during that time. take this for example. tahm kench eats friendly tristana who is a very poor spot, but he gets caught for saving her. he loses all his HP, shields for his full health bar, and but still falls to survive or make it to safety! tristana reappears, losing about 20% of her max HP. i just feel like this is a cool mechanics idea to add more risk/reward as to when to use an ability, because there arent very many drawbacks from eating an ally, because you generaly only want to eat them when they arent in a position to safely do damage anyways, JUST A THOUGHT, tell me what you guys think? sorry if it doesnt make very much sense, just writing some thoughts off the top of my head.
