Sleeper overpowered champions

Mostly tanks dealing assassin-level damage.

Mostly tanks dealing assassin-level damage.
Gnar, Olaf, Darius, Volibear, and Udyr are fighters.
Rammus and Zac are the only tanks in there.
TBH, doesn't matter what they're classified as when they build full tank anyway and function that way. Leona's a dedicated tank and deals zero damage. She isn't more tanky than any of these "fighters". Why are these fighters allowed to build full tank and retain their damage?
Not sure which game you're playing where Rammus and Zac are doing assassin level damage.
Also Anivia is highly played on the pro scene so wouldn't call her sleeper.
DONT TELL PEOPLE ABOUT THE BIRD!
She's how I do ranked, and I don't want peeps to know how to deal with her
:)
I agree with Zac and Rammus, they feel overtuned. Udyr is disguting but idk. Gnar.... idk really, he seems ok.
Yeah bro. Zac and Rammus are just straight out dumb. Udyr is beyond retarded.
Nothing is more aggravating then getting 0-100 by E R W full tank Zac
You forgot jax, his new passive buff + Trinity change makes him stupid good.
Added. For sure.
Juggernauts, not tanks.
Tank is a champion who is initiating, the CC dealer like

These are Juggernauts - Damage dealers without strong CC with some tankyness, and small mobility.

Aaaand yes, juggernauts are pretty op this meta. But this meta everything is op ;/
Chogath and Sion are juggernauts, Rammus and Zac above are tanks.
Anivia has way too much reward for a skill floor that is literally in like sub-basement level 3. Got to gold with an over 70% winrate she's total freelo.
I always thought she was dog until I met a good one in lane. Can't do jack vs this champ.
Kayle is OP but people don't realize it, with QSS gutted Fiora is pretty broken again, Anivia I agree with, and Sion is strong.
Yeah man. I've played Kayle a lot, the problem is she's super late game. You need like 3 items at least, but then you start melting faces. She's boring as heck to play though, so I guess that's why she remains mostly unplayed.
I've been seeing a lot of are gnar volibear & jax, not really sleepers so much as popular again. Gnar can also be an off-marksmen.
