D&D 5E Proficiency with Special Weapons?

[Phoenix8008]

So if I'm reading this right, there is no way to have proficiency with any special weapons. No feats, no skills, no maneuvers. Maybe this is something that is planned to be added later? So you can use any of them, but always at disatvantage.

You can bet there'll be a way, but probably this time not through feats.

How about just as story reward? Or maybe a rule of thumb for swapping proficiencies.
