Without getting too deep into any discussions here, I just wanted to add my voice to the pushback against the changes to Marksmanship by linking a reply I made in another thread:
And, so as not to repeat points already made, emphasize that I strongly agree with what the OP said there, especially regarding the key differences between the specs that make BM an unsuitable substitute.
Many other points I agree with can and have been said by others. But to keep my input simple, I sincerely hope the devs reconsider this rework, because it effectively removes the original, much loved hunter playstyle and fantasy from the game entirely.
