Horwath
Legend
There is one simple reason why potions/oils were promoted to Bonus action usage.
Drinking potions is not fun, both mechanically and thematically.
Because of that it leaves Action window open to do something impactful and "more fun".
now can you chug down an oz of fluid in a second? yes, it's a glass of shooter. With a little practice, which adventurers do have, pulling it out of specialized potion belt and plug cork, you could probably do all that in 2 second.
but maybe we should all have those "water bladders" that you have in backpack for hiking with a drinking tube.
load the bladder with 20 or so healing potions and you are good to go.
now, that I think about it, it was in 3.5e book somewhere, just need to look it up when I get home.
