Very good in-depth explanation why Larian messing with the rules this much won't make it fun for most players with 5E background.

Though honestly I wish they'd give a statement already, even if they just said "we won't make it our priority to follow 5E rules".
Because then we could stop arguing here and instead focus on preparing a 5E community mod that fixes all rules issues (and maybe also renders all barrels and surface effects that don't come from the PHB inert while we're at it).
