Because people apparently cannot understand how it works and try to fight it and complain, juggler was mostly disabled now.
- it wont split any game (you can have 32ppl small teams now)
- it wont auto enable if you join managed host (with star in ZKL)
- it wont try to put clan members together
- it wont divide players be elo
- it wont try to save "too small" games by sending people there who like this type same as their current game
If you still want to play proper small teams, you have to manually enable quickmatch (click on quickmatch button and set your preferences).
EDIT: Actually detrino had an idea for "split on start" so now it experimentally splits small teams at start if size is over 15
