Zul'jin is set to enter Heroes of the Storm's Nexus after Ragnaros in January, but before then, you can get a good look at his kit in the video below. His main gimmick involves doing more damage while his health is low, living on the razor's edge constantly. We'll see how people deal with him soon enough, and whether or not his survivability will allow him to keep wreaking havoc before he gets bursted down.
In other news, Chromie is getting a Genie skin, and Kharazim, a woefully neglected support as of late, is getting a tiger armor skin people most likely won't use. Oh, and a troll wouldn't be complete without an Amani bear mount.
I've been waiting for a troll to arrive since Heroes launched, so hopefully he goes over well! The whole "Warcraft assassin" thing is getting old though, even if Warcraft is Blizzard's big money maker.
