A few of us in the hunter forums have come up with different ways to return an updated version of the spec back. Ghorak made a popular thread and I made one about a month ago for fun.
I think if it does eventually come back it needs to fit more into the modern game, but I absolutely agree with you. The face paced reactionary gameplay where you had to make quick decisions was a blast to play.
I need to update it a bit. I’m not sure I’m entirely happy with a few things in there, but if you’re bored / looking for something fun to read about what an updated version could look like, give it a read
