There’s many ways to go about that IMO. I could easily see them making something based on the dark rangers. However, this is something I went into detail a few weeks ago for fun, so I’ll just link that thread here. It has themes I’d enjoy, base spec and how it might function, and talents. Obviously I don’t expect blizz to ever do an idea copied like that and I’m not exactly sure how balanced all of the ideas would or wouldn’t be.
Feel free to read through and comment though with thoughts or feedback ^^
