TFT suggestions

I've only started playing TFT for a week now but Kennen and Draven feel absolutely busted. Along side a lvl 2 or higher Morgan. Feels unbeatable(assuming you also have a good team comp) I think the RNG needs to be tuned a bit tho. Cause it feels like no matter what you start building those champs dont show up until after second carousel. Even if you're going gunslingers with trist and graves. Both 1g which means they should show up more often. If there was a way the game could see what comp you're trying to build and just skew the RNG towards that comp by like 4-5% that would lessen the effects of getting screwed by RNG an make the game more skillful. But you still have a change to pivot without an abundance of the comp you already have... ya know? Again just from my perspective and I've only been playing for a week. Lemme know if you also experience this. What's you're viewpoint?
