On a Ranger, twf is usually fine lvl 2-10. Even beyond that if you multiclass with Rogue. But in BG3, the problem is that they've not only thrown the BA balanse out by making hide and shove BAs, but they added things like dipping and a number of abilities to offset the penalty from Great Weapon Master.
So it isn’t like twf can't perform, but man if it isn’t far from optimal as things stand right now.
