DotA 2 is one of the best MOBAs (Multiplayer Online Battle Arena) around. Based off the fan-created Defense of the Ancients mod for Warcraft III: Reign of Chaos by Eul, Steve Guinsoo Feak and IceFrog (who now serves as the lead designer for DotA 2), it is considered the most actively played game on Steam. Though it follows a repetitive style of play, it is still a fun and challenging game to play, despite some of the criticisms levelled towards the allegedly inhospitable community of players. As with the original DotA, this game is frequently updated, with bug fixes and Hero and gameplay changes introduced periodically. As of this writing, there are 109 possible Heroes to choose from, with Oracle being the most recently-introduced Hero. One of the biggest criticisms towards the game has been its steep learning curve; called by some a learning cliff. Part of this stems from the difficulty of mastering certain heroes, or from certain Heroes being generally imbalanced. This is where this article comes in. It will discuss the ten most imbalanced Heroes that are in need of a rework. Whether it is one spell that needs changing or an item combination that makes the Hero too difficult to deal with, what matters is that these 10 Heroes need to be re-visited by the developers so that games dont become decidedly one-sided.
