Kog'Maw Passive Same But BETTER Idea

From my experiences from playing Kog'Maw people just tend to ignore its passive as if nothing happened "Meh, I'll just eat the damage, no biggie" or "I'll just flash/run/dash away from it, no biggie"

> For every minion/monster devoured grants 1 stack of Satisfaction (2 for champions). Upon dying, Kog'Maw gains movement speed and detonates after 4 seconds, dealing 100 + 10 per level + 5 per stack of satifaction as true damage to surrounding enemies and expending all stacks of satisfaction. > Kog'Maw may attach onto an enemy champion upon contact, slowing the target by 50% for the duration of the passive and dealing damage only to that target upon detonation. > Upon detonation, Kog'Maw's explosion applies a debuff to enemies in contact to take 5% increased damage for 3 seconds from all sources.

This gives Kog'Maw a choice whether to deal an area of effect to whoever it closes to but leads to a possibility of getting no one

OR

Kog'Maw can choose to leap onto an enemy if nearby and never let go. Kog'Maw's void ooze spilling from its mouth causes the target to be slowed by 50% and only deal true damage to whoever Kog'Maw choose to latch onto.

I want enemies to take heed on how Kog'Maw can drag someone down other than attempting to execute whoever takes damage "Oh god, get away from that thing". This makes enemies want to kill him but stay away from the moment it is about to die. The fact Kog'Maw damage scales from how many it kills makes enemies more anxious to take Kog'Maw on. The longer Kog'Maw continues to feast upon its victims, the more potentially dangerous he can be.

I also view Kog'Maw as someone who shakes salt and pepper before it starts eating and a thing you would struggle running away on empty stomachs (yes I think he has more than one stomaches full of acid. Dying causes the stomaches to collaspe and react with each other and lead to a chemical chain reaction aka explosion.) The explosion causes the enemies in contact with the acid to be further digested from the acid therefore taking amplified damage from all sources, giving enemies a bigger reason to avoid Kog'Maw!

I am currently liking the Kog'Maw update nevertheless, but I think its kit can be further extended to make him shine and promote more players to play the Void Devourer while it still carries its downsides
