Any Ideas on how to fix Kog'maw so we can actually play with him?

I could come up with some ideas but I kind of want to know other people's opinion about him.

I myself would rather have something in place of his Q. For those I can kill, I rarely need an extra damage ability. I would like to have a void bubble come up around him that absorbs damage. Or better yet, an ability where he opens a rift hole beneath him where he falls into it for a second or two becoming untargetable and being unable to attack while in the hole. It would just be good enough to dodge an ult like a Jinx rocket or half of MF's bullet time. He shoots so fast, sometimes I want to be able to shoot projectiles out of the air clay pigeon style.

He would still be immobile but not a complete sitting duck for someone's entire combo. There always has to be someone on the bottom of the food chain but does the disparity have to be so large?!?!?! Is there any ADC he counters? What happen to rock paper scissors?
