(Not to mention the disingenuous "it's not D&D 5e rules" but the "Love the disengage mechanic" or the "don't use it if you like it" that makes me think that you really don't understand the problem as a whole)
You were suggesting that using your hoembrew rule ,+1 or +2 for height advantage, would be better than Larian's usage of advantage for high ground even though Larian is using RAW(Rules as Written) (Pg. 173 of Player's Handbook "The DM can also decide that circumstances influence a roll in one direction or the other and grant advantage or impose disadvantage as a result."
You are being disingenuous when you argue Larian is homebrewing when you are really arguing against a Rules as Written implementation of advantage.
I gave you facts.
Those facts limit our creativity, our choices, our tactical possibilities, the (tactical) depth of the game, the replay value of the game, the control we have over our characters, they create balance issues, and so on...
No. Those were not facts. The game doesn't change how I play D&D nor does it force me to play in a certain way.
It all comes down to approach. Role-Playing vs. Gaming Computers. I am a role-player who does things that make sense for my character to do.
That means long resting every 10 or so combats and only when I am out of resources and in a safe spot. That means not carrying around full barrels of explosive liquid because that's just silly.
That means not eating pig heads in combat because it wouldn't make sense. It means not hiding in combat because I'm just beyond and enemies vision cone.
The game is in no way, shape or form balanced around my characters doing those things.
I remember in earlier installments of BG folks would cast cloudkill at the edge of the fog of war and wait while the enemies died and thought themselves clever. I would never do that because my characters didn't know what was on the other side of the fog of war. Even though it was an "optimal" way to beat the encounter because the enemies couldn't fight back. Even though the game rewarded you for doing so.
There are those who think they aren't being optimal unless they exploit game mechanics. If that is all they do then of course they have chosen to limit their creativity and chosen to ignore the uniqueness of the classes.
There are those who role-play their characters. Each character is unique and you need to use all your abilities to be successful.
Just like any good game of D&D.
