PL, drow, wisp and centaur, for sure.

sven is surely an op hero, cmon he got cleave by passive and an unbelievable unbalanced ulti that gives him possibility to carry the team and get easy kills without farming is just such an op carry with easy kills-abilities

traxex is the most OP hero, high aspd and damage, have silence and in higher lvl, no-stopping slow
and all that in ranged attack.

At the current patch, i would have to say Phantom Lancer is as overpowered as it gets. Provide him with just 5 min of farm and he's all set to take over the mid game and dominate late game.

A good lone is pretty ridiculous and Pl is all about countering so in a pub its really easy to go bad and still have 2-3 chances to pull off a victory

nature's profit and cancer lancer.....it depress me to see them pick on other side

The most Imbalanced hero is PL as well as that Bristleback u just canot stop them late game if the player behind them is verry good so frustrating they need to be nerfed not so much dmg reduction and not so much ilusions that has to be done cuz not only the ilus Pl has alot magic armor too and that makes him even more OP as well this Birstleback u dont have to deal only with his back and spikes u have to deal with his speed too...

Drow Ranger, in my opinion. I'm a relatively new player, but she is a popular hero because she has 2 spells: a silence and a slow, making it hard to cast on her and hard to escape. She used to only get 20/30/40 bonus agility from her ult, which is OP but not too ridiculous, but now she has something like 40/60/80 bonus agility as long as you are outside of a 375 radius of an enemy, making her almost impossible to out DPS as a ranged hero, and a melee hero has trouble getting close, making her quite ridiculous in low-tier games.

i would have to agree with most of the guys here, i think that cent is really imbalance right now with his ult and tankiness he can surely change the tides of a teamfight, and with his very strong early game nuke. his pretty good in all stages of the games may it be early, mid, and late. so yeah his pretty imbalance i think.

I would probably say it's Naix right now, or even SWM.

Yeah, probably its not the common opinion, but to my mind the most OP character in the game is Meepo.
Yea, not dat drow ranger, that is getting ganked really easy, not that centaur, that can be countered by a lot of nukers.
Meepo is just perfect on any mode if you are good with him(my own experience.)
He can recieve farm x2, x3, x4, x5 faster that any hero on the battlefield.
Yeah, someone will tell me that if team will concentrate on just one meepo hes easy to be killed.
BUT GOOD MEEPO WONT ALLOW THAT. Good meepo will use blink dagger and put a hurted one away, and own.
I think meepo is really hard character to play, but still hes op and a choice for pros. As the +, i dont really think hes going to be fixed by another patch, because there are a too few amount of players that can have advancement with him.
Awesome hero. But still op.

there is no unbalanced hero by me, its just if u played it well, it will be strong, just use the skill set wisely and good teamwork

The main reason maked you guys think its imbalance is the TEAMWORK !!!! can u go ganking with naix without support like NP or hero had blink?
