Arthas is overpowered, something I didn’t think I would ever say. He was one of the first heroes in HOTS and has always had a rather dull selection of talents and skills, until now! Let’s start at the beginning.
Heroes of the Storm has just seen a new patch, Chromie has been added and Arthas and Anub’arak have been reworked. However, it seems that Arthas may have been reworked a little bit too much. If he isn’t already a first pick/ always banned hero by the time you read this, he will be soon after.
The problem lies in Death Coil. By talenting for Death Coil (taking Deaths Embrace, Immortal Coil and Deathlord) then Arthas can regenerate 24.50% of his total health every 7 seconds. As a tank then this is obviously incredibly strong and when combined with his other regenerative talents and skills such as Army of the Dead, he is almost impossible to kill. There is an excellent reddit post on the subject to be found here.
As Blizzard do not usually issue patches immediately, it is likely we will have this version of Arthas until next week.
