Infernal dragon should get removed
It feels really bad to play against infernal dragon they can get up to 24% additional attack damage and ability power from 3 of them. Also if they have elder dragon it gives them 36% increase (they also have the true damage from elder dragon) making it almost impossible to fight the enemy and contest baron/towers with them until it is over. Even without elder dragon it still is a pain to play against it compared to ocean, cloud, and mountain dragon which are fine to play against but I don't like infernal dragon.
