I read reviews of many users who managed to study the Demo, including from the user
Goffterdom (on page 8). All in all, I see one common complaint - boring Zul'jin. I myself cannot appreciate his skills, because I'm just glad that I can finally play for this character, even if he has no skills at all.
But I'll show you something, maybe it will inspire you. In the previous WoW add-on - "Battle for Azeroth", there was a new system called "Expeditions", which allowed sailing to small islands, many of which were a reference to the second war. So, on this island, non-player characters fought against the players, who had an improved AI, which partially resembled real players.
And one of those enemy characters was a Forest Troll named "Berserker Zar'ri" which was a direct reference to "Zul'Jin"!
You can read her skills on Wowhead, namely: "Berserking" (increases the rate of fire and damage), "Taz'dingo!" (immortality for a few seconds), "Throw Axe" (An axe that bounces to other targets on impact) and "Twin Cleave" (axes that reduce the movement speed of enemies).
