Agreed. But I think the issue there is without making new abilities, dark ranger has had its abilities farmed out to other classes (similar to blademaster, etc.)

Silence is on priests, though I can see a version being made that is a targeted arrow shot like Sylvannas's HotS ultimate/raid fight ability.
Black Arrow went to Hunters, though I am not sure if its still there.
Life Drain went to Warlocks.
Charm went to warlock pet Succubus.
Again, its not to say they couldn't do something that combines Dark Ranger, Priestess of the Moon, and Shadow Hunter into a single class (since they all seem to be variations on the same theme largely determined by race --- an archer assisted by magic) -- I just personally don't see it happening.
If you were to look at both Tinker and Alchemist, their abilities include:
Tinkerer
Pocket Factory
Cluster Rockets
Robo-Goblin
Alchemist
Healing Spray
Chemical Rage
Acid Bomb
Transmute
If you go into the tinkerer teams in BFA (Gazlowe's Greasemonkeys for this example) you've got abilities like:
Heal Bot
Arachnobomb 2.0
Rock-It! Turret
Shadowy Decoy
POW-R Amp Platform
This to me seems like a combination of the Tinkerer and Alchemist --- there are 3 specs on the team, a mech Tank, a healer, and a ranged dps
with the exception of the decoy, none of these things really step on modern in-game engineering
As for the other abilities and how they might work:
Robo-Goblin - a cooldown buff increasing your power
Chemical Rage - Another Bloodlust
Transmute - a polymorph/hex effect that turns them to gold rather than a sheep/toad
Heal Bot covers healing spray
Arachnobomb 2.0 and Rock-It! Turret cover pocket factory and Cluster Rockets
The decoy has in-game predecessors: Stoneclaw, Statue of Black Ox, etc. etc.
just my 2 cents
