I'll just echo the general sentiment in here that these are all great ideas, but I want to preserve the 2-way setting for fictional leagues. I'd actually say the best way to do that is probably give us a few more settings for customization, or in other words, allow us to specify just what percent of incoming players will be 2-way players, though for a realistic level it'd probably be such a small modifier I'm not sure how to format it, you'd probably have to take the significant digit out pretty far, but that's like probably the very least concern regarding that proposal. On the flip side, if someone wants to run a fictional league where everyone's a 2-way player, well...
If such a setting already exists, my apologies for overlooking it, I've not messed around with that area much.
