Counterpicks always have been a problem. When a champ kit make another one useless, then you start the game with a huge disadvantage because you can't exploit your champ.
For example : Irelia vs Poppy. There nothing you can do. Poppy W make entire Irelia kit useless and not a single item help vs this situation.
Squishies melee champ vs 
or 
... Impossible to lane vs, and even farming is hard. 
isn't the biggest problem. Teemo is squishy. I have beaten him with 
.
For me the problem is who have more HP than you, deal insane dmg and who are super safe + who can poke you easily too.
Teemo is a joke when you compare to them. Have you ever played 
vs ? Impossible matchup. If i try to engage, Vlad put his W and escape while slowing me and dealing dmg with his E. Then he regens his HP even if i buy 
.
- Camille is squishy and seing a ranged Vlad being tankier than me is horrible.
vs 
. Except playing undertower, there nothing you can do. You can even get towerdived.
top may be annoying but in most case, she is useless, let me explain why :
Vayne is squishy. She is not Vladimir with his 3000 HP pool and 500 AP with healing. If you engage her with your jungler, she is dead. You even have tanks like 
who can engage her easily with their ulti.
Picking Vayne top mean that the enemy team is likely to have no tanks or no frontline.
Vladimir can be frontline. With all the Hp and dmg he has, there is no problem for him to be in front of his team. But Vayne ? She can't. And if her team lack of tankiness, they will lose on composition.
It's the same thing with Teemo. Teemo is squishy. If you pick him, you must be 100% sure you will delete your opponent because you lose on team compo. Teemo has nothing to teamfight correctly.
are the biggest problem in top lane. More than Teemo and Vayne.
Ryze and Vlad are tanky, deal big dmg, can regen, can poke and they have a decent teamfighting.
Kennen may not be tanky but compared to Teemo, a flash Kennen ulti with protobelt is a winning teamfight.
And Kayle ulti is OP. I've never seen such an OP ulti as Kayle. 3s immunity to dmg + big zone dmg. Paired with any champs who can engage, this ulti is a massive "free win".
Couterpicks are more problematic now because there is no more defense options. Laning vs Vlad as squishy melee ? What can you do ? You can try to go magic resist but you will lose dmg or you won't have armor to tank the adc...
While Vladimir only build 
and AP items and he gets 4000 HP with a lot of AP. + He has no mana cost!
Because you have less defensive options, you must recall more often and turrets give golds with plates. So your opponents win on the pick and not on the plays. He win because he picked a strong champ that counter mine, i'm forced to recall and he can free attack my turrets and free farm to gain gold.
And now with Drakes pressure, Top lane isn't interessing if you don't have a good matchup.
into 
you lose. Period. There is not one single thing you can do that game to beat him if he's with 5 kills of you. You just lose the matchup and you can go fuck yourself if you want to be able to do anything about it.
