Kog'Maw Somewhat Adjustment

Is this the right board for league ideas? Anyway Kog is a very OP champ right now mostly since it's ardent meta But he is way too easily countered by alot of champs mostly when your support can't protect you in time So if you're out of position in any way you are already dead Which logically means he has high damage in exchange for his immobility His passive probably needs abit of a change like a bonus mini passive I mean his passive right now is already very very useful to burn a summoner spell or even finish off an enemy (but since every second champ now has a dash it doesn't really matter) But the passive is useless mostly because it requires him to be dead to actually execute it... His new mini passive should be something like Excitement - Attacking champions increases Kog'Maws movement speed slightly stacking up to 5 times or something (kinda makes sense since hes a void puppy and puppies get uhh excited when you play with them??) Now this might just make him even more OP than he is right now so I'm guessing decreasing his damage abit would be fitting? But if that happens he is gonna be COMPLETELY useless (mostly if his W that he deeply depends on gets nerfed cause without his W he's not able to do anything...)

Show some love for the void puppy and give him some mobility before zed oneshots him in 0.000001 seconds while your Janna support is shielding a full HP Malphite please teleports behind you Nothing personnel kid
