Counter-heroes in duel mode (3.1).

Well, he also has his weaknesses, I'm sure of it. Of course, he's a strong hero, especially against mass-casting heroes like Knight, Deirdra, and Leto. But he's weak against heroes with innate, skillful defense, like Shax, Airia, and Marbas. Although I haven't tested him much, I feel like many players can beat him now, even Deirdra, for example. Simply using the right runes and defensive tactics can lead to victory in a battle against not-so-experienced "Uber" players.
By the way, I almost defeated Helmar with Deirdra recently, and I almost succeeded, but then my boss showed up.
