You had a nice, succinct write-up. I just threw in some comparisons for BL1 veterans who might not know what had changed.

Some people really liked the BL1 weapon proficiencies and were thrown off by their exclusion in 2. It was a good move on Gearbox's part, if you ask me. While it's slightly annoying that the BA token choices seem to be random, and thus may not include any traits I find desirable, it's still worth doing. Being able to pick the same stat for each token might make it a bit overpowered, and I think that's why they keep you from focusing too strongly.

It's a neat feature that's unique enough that it might attract fence-sitters.
