illaoi nerf idea

so I have been fighting much more illaois than i use too and have realized why she is so strong. what i think could really help her is nerfing her tentacles one idea is making the dmg on the first tentacle does 100% dmg than all subsequent tentacles do like 25% to 50% dmg and not have te healing stack on them either you heal for each champ hit not each tentacle hit it would make he weaker late game but she would still be a great team fighter late game because she is tanky and has sustain. what do all of you think about this do you think it would make her too weak or do think it would just balance her.
