ranged ranger 17/BM 3
horder breaker, volley, swift quiver, sharpshooter, combat superiority, action surge.
Yes, fighter are better agaist single target but you can burn the boss and the minions at the same time.
melee ranger sucks.
Bah please, ranged Ranger 9/BM 11 (not in that order).
Horde Breaker, Crossbow Expert, Sharpshooter, Combat Superiority, Action Surge, and three attacks base (take that Swift Quiver!)
Sure you've not as much at-will group control (other than Horde Breaker and simply targeting a different creature with each attack), but you've more individual attacks which gives you more flexibility. Plus Action Surge does more. And you still have crowd control spells.
