I wish I saw more Kog'maws in this META.
This is what he's made for, shredding tanks. Yet, almost no one plays him. It's really disappointing not seeing my cute little monster ADC who shits on anything in his path if you peel for him.

because he is better at mid right now then ADC. a lot better
Why play him ADC when you can go mid with luden's and get freelo lol
His winrate is actually 49-51% in all ELO brackets. He's definitely not freelo and is in fact one of the hardest to play well unless you only pick him in ideal comps. You also sacrifice a lot of snowball potential early since he shouldn't be getting kill pre-20 minutes unless his opponents are really bad. With a Katarina, Yasuo etc. you can get fed earlier and win the game there instead of hoping to be a big threat late game.
Because he needs massive amounts of protection from his team, even late game with 6 items.
He is a contested pick in LCS, but in SoloQ, where no one forms comps (he really needs a comp formed around him to be used to full effectiveness) and laners would rather try to make level 5 #BigPlays and fail and end up losing lane hard and feeding instead of playing safe early and letting Kog's hyperscaling take care of mid-late game, you really can't make him work reliably. Yes he is amazing when he gets a team that guards him and wards and waits for him to land enough R's before they start the teamfight, but he is equal magnitudes garbage when he gets a shitty team that feeds to the point that he gets his lane camped, or would rather go farm the raptor camp instead of help him take a turret etc. When you are playing Koggles, you are leaving your chance of winning in the hands of your team more than any other ADC.
Meanwhile the other tank shredding ADC, while not being anywhere near as good as Kog in teamfights or sieges, is perfectly capable of handling herself and often doesn't even need her support guarding her, her much lower reliance on her team's protection makes her the superior soloQ pick. 
theoretically is the best of both worlds of Kog and Vayne, as he is a functional assassin while also being a teamfighting monster, but it literally takes him 5 years to scale up to that point, and as such he is absolute torture to play when behind. He also lacks scaling mixed damage and %HP damage, so he isn't the best equipped to deal with tanks.
