Gameplay balance and design in a PC game always has to come first. This is not a religious sect with expectations of strict adherence to some holy text. A game must be adjusted for proper balance and working gameplay experience in the medium it's designed for regardless of what some rulebook states. Where 5e balancing or design fails to fulfill balance and gameplay needs for a PC game, Larian SHOULD homebrew. This is not a tabletop game, this is a PC game inspired by a tabletop game. Keyword inspiration, not an exact copy with pixels.
No one said Larian shouldn't homebrew, so I'm not sure why you're saying this. In fact I even said I think some of their homebrew is good (weapon actions, some of the nerfs to some CC spells though I think they went TOO far with some of them, etc.) Even the shove shenanigans are mostly fun (though, you know, it does turn shove into a save-or-die spell whenever you're around chasms.)
What ISN'T fun, what feels absurd, is how OP the items for martials can get and how many CC spells are outright *bugged to make them weaker than they should be even within Larian's homebrew*. Some of these are outright inexcusable honestly. Not to say that casters don't get some absurd items too; but they're basically absurd items that make magic missiles into something with humongous damage output for some reason. Between the nerfs to CC and outright BUGS to CC and the blatant, overpowered per-missile buffs to MM it really feels like Larian is pushing casters into a really boring, damage-spamming build, something their martials can do for free (without burning spell slots) because of the crazy items they get access to.
