Late to the party but it is sort of idiotic to just ban it entirely. If you want to play in a world where it is disallowed, fine. Some people like it and the option should be available for them in their worlds.
This happens with every friggin' issue... people want to remove all flexibility an owner has. I have seen so many posts or world chats denouncing cash in trades, tandem pitching (which we let them partially kill with the PC settings), tanking (I join in bashing this one because I think it is lazy... but it is a strategy nonetheless. I just try and avoid worlds that let it happen) and probably a slew of other things I am just forgetting right now. Everyone always wants to come up with some new change to the game that takes away another owner's ability to think outside the box and/or try to give himself an advantage. It is a game and it is about creating an advantage for yourself.
You also have stuff on the other end where people want all these new additions that basically has the computer do everything for you (manage minors, hire coaches, blah blah blah). People also just want to pick a few players they like and not do any management to try and maximize that team's output. I realize this part is a little off topic but it falls in the same realm to me... which is that a lot of users want to make this a dummy's game that ANYONE and EVERYONE can win and not just the people who work to earn their wins. This is how society regressed to the point that every little kid gets a trophy, cheapening those that went to the kids who earned their wins.
If they want to add a bunch of customization for commissioners to allow him/her to establish hard rules (in the system rather than just explained), fine. I will stick to worlds that allow owner freedom like I do now. If we allow the vocal minorities to ruin this game by taking away all the freedoms of owners in every world and essentially turn this game into SimLeague Baseball (where you basically just check scores and do nothing else), then they can count me out. Options are the magic.
