I have to entirely disagree with this suggestion. Reason: it’s rather ridiculous.
I’ll explain.
We are Marksmanship Hunters. Master Marksman and Snipers. This is the Long Range Specialization built for those looking to pick off targets at a distance.
Our Rotation has us focusing on using a heavy hitting Aimed Shot, which can make some heavy numbers in damage (My highest hit on Zek for over 240K https://twitter.com/MrPocketsPlays/status/1062548683000963074 )
This is because we’re Snipers. Not ninjas. You don’t see a world class marksman suddenly pulling out twin swords and doing ninja flips all over the place throwing shuriken and yelling some sort of attack from Naruto. They simply put bullets in targets from far out with a boomstick. So the thought of making MM hybrid or melee is at best outlandish beyond belief.
However. I can countersuggest some things you may find entertaining with the idea of a rogue in mind.
1: Camouflage becomes Stealth for MM Hunters. Without the healing, it could become a very amazing tool for MM’s to get into position with.
2: Careful Aim gets baked into the spec.
3: Increase our range by mastery. This is our primary spec tool, and it only raises our range by 5 yards… that’s a shame.
