who is the worse dotA hero that you had ever played

Dota heroes abilities are built in such a way that each has its own strengths and weaknesses. Although there are balancing issues that create underpowered and overpowered heroes, there is no single hero in Dota that i can consider useless. But you are going to ask me which hero i am bad at, I'd say Visage. I'm not very good at micromanaging, his skill set does not support my gameplay well and I don't get the result that I want when i play him. Still, I know dozens of guys who own with this guy so i can't consider him useless.

Well in my opinion the single most useless hero in Dota is... you guessed it, Spiritbreaker. His charge can be easily seen through when you see that you have the effect on you when he comes close. Basically it warns you that he is coming so you can TP out. He has a terrible early game when his attack speed is slow and he can't get any bashes. His mid game is ok I guess. His late game is terrible because he gets owned by disables and most other late game carries do far more damage than him. He is ok in a one on one fight late game because of his bash but in a teamfight he will get decimated. Anyway this was my opinion on the most useless hero, happy mylotting and keep playing dota guys.
