This is perhaps the missing ingredient. Given the breadth, power, reliability, ease of use, etc. of D&D magic, then narrative power could be a way for martial abilities to bridge the gap a little.
You can give this narrative power to the DM if you want to make things a bit more traditional.
So something like Come and Get It just doesn't go far enough. The ability could be designed to be more open ended so that the effect is everyone within 30ft ends up next to the Fighter and they get 1 attack each. The DM decides what this looks like depending on the circumstances --
- perhaps the Fighter runs over and headlocks the enemy Wizard and drags him, then taunts the minions into bum rushing him
- perhaps the Fighter weaves in and out of the Giants legs causing it to stumble forward, then leaps up and grabs the Strige yanking it to the ground for a strike.
Using this ability forces the DM to make it work if at all possible to get the effect, even if unlikely.
But the means to get the effect do not have to play within the action economy and the DM can make the environment comply to make it happen.
The same thing could be used for things like action hero movement -- Action Hero Movement -- you move from point A to point B within 120 feet if at all possible. The DM can manipulate the environment to make this happen (E.g., vine comes off and you swing over, the dragon swoops down and you jump off its head).
