I think the consensus at the moment among gamers is the Larian mechanics are too over the top compared to D&D core rules and should be toned down. And if we keep commenting on the matter, they might eventually tweak some stuff.
Personally my concern is barrelmancy and hoardermancy being so powerful, it will overshadow spells like fireball or cone of cold. And it would be quite sad.
I wouldn't call it a consensus. In fact, the players hardly agree on anything, just go to the Steam forum, it looks different there than here. And as for overshadow it won't be a problem (at least for most), the game doesn't really give you any reason to use them, unlike the broken height advantage (trying to avoid it is hard). If someone really takes care of stacking barrels, and at the same time hates this mechanic, he will spoil the game himself. The game as it stands is very simple.
