Developer Comment: These changes to Kel'Thuzad are being made with two goals in mind. Our first goal, which is in line with many changes we make, is to improve talent diversity. We've moved Glacial Spike into his baseline first quest reward, which should both help his Level 7 talent choices as well as open up new build possibilities with the increased flexibility on that tier. Second, we want to slightly reduce his variance and increase his reliability. We've moved most of his cooldown reduction reward baseline, and with Glacial Spike being his first quest reward, he can now combo enemy Heroes anywhere in the field, without needing to rely purely on having other enemy Heroes or structures nearby. In exchange for this, we've removed some of his burst damage and the ability to use Chains of Kel'Thuzad on structures. While chaining enemy Heroes to structures made for some cool moments, it could be oppressive to play against, particularly on maps with large pushing objectives like the Punisher on Infernal Shrines.

Bug Fixes

Developer Comment: As expected, there is a fairly large discrepancy between Kel’Thuzad’s performance across the entire game vs. players who are getting experienced with him at a higher level. His win-rate has climbed more than most of our other releases as players get used to his kit, so most of our changes are aimed at talent balance and toning his power down. While we like the sharpness of his power spike due to Master of the Cold Dark, we’ll continue to keep an eye on his burst potential and his overall strength going forward.
