I mean, it still feels broken, but it seems WAI based on the past?
It's not working as written. Your point (assuming it's true, which I do but hadn't noticed on my own since SLKR goes through PvE content so quickly that any time I've had to face Imps in GCs with SLKR I probably burned them down so fast I didn't even notice the bug) only highlights how long they've had to fix it. They could even decide to simply change the text, which is ridiculously easy. But they can't even do that. So I went in with Jango lead BH, Killed Veers, and that only had the effect of clearing burning off of him. Wasted 20 energy because they couldn't be bothered to write the description correctly.
Now, my Jango is only lately usable since I don't care about BH and my Jango sat at g9 or so until GLOW came out. I've had relic Jango for about 2 weeks and therefore never had a reason to examine his behavior in GCs. Sure, I **could** have figured out their bug sooner if I happened to like BH. And I **could** have kept my own list of CG bugs to plan around CG's problems either describing abilities and/or programming abilities correctly (whichever it is).
But I rather think that's CG's job.
I also think this shouldn't be considered to be WAI, since I think writing english language sentences is easier than coding and also because there's just no reason this Imp ability should ignore abilities that prevent revives, but I do realize that that is my opinion. I'll work with whatever the rules are, just so long as you don't deceive me about the rules on something as important as the zeta abilities of a required faction.
