I like the Divinity engine. But I agree the starting point should be core 5e D&D rules before moving forward. Currently everyone is arguing the merits of the homebrew stuff vs the 5e rule set that hasn't even been implemented. How can you argue something is better/worse if it hasn't been tried? Make barrels heavy so you cannot pick them up. If the 5e rules suck in game then change it but at least try.
