As long as you understand that 2d6 yields more reaults in the middle than at the edges, it’s a great tool. Just put things that should be more common in the middle and less common at the edges.With regard to using 2d6 (which generates a curve that will generate certain values more frequently than others). I think it's worthwhile to note that a curve is better for consistency, while a linear progression (ie, 1d12) will provide greater variety. There's nothing wrong with either approach (it's a subjective preference) but worthwhile to think about if you haven't given it previous consideration.
