Since TWL is rapidly approaching (even if it hasn't been decided when it starts yet) and TWL pretty much kills TWD:
Add player borrowing feature to TWD. For dd/jd you could borrow 1 player, for bd 2 (or more, up for debate). Alternatively only allow borrowing for basing since dd/jd requires just 3 players nowadays.
Often when your squad manages to scrape enough players together for a game you can't find an opponent (especially for TWBD). And by the time you get an opponent someone has logged off. Or you get challenged but you're missing a player or 2. This would alleviate that problem and boost TWD activity.
Rating could be disabled for matches with borrowed players in, if it is deemed to be a problem. Maybe add a command to the bot that both teams have to agree for borrowed players to be allowed in the game.
