Interesting development.... I noticed that ☜❽暁❽-, who is the lone human team in II.4, has sold all his players, has not signed in for 10 days, and is now forfeiting games. All the other teams in II.4 are BOTs so, this should open up one additional promotion slot for a second team from one of the other div II leagues.
I'm not sure how the computer selects the other team but it would be the remaining team that was most competitive based on some algorythm.
So, with that, here are the teams on the watch list:
II.1 - Bully Sharman
II.2 - Tokyo Thunders, itoh-sama, Leaf team 7, Isehara Pistons, Mythical Man-Mouth (1 game seperates these 5 teams, This will be very interesting how this turns out.)
II.2 - Fire Country Trailblazers
II.4 - fumoffu platton, II.2 team from above, Shikoku Otaku
However this turns out it looks like all 4 teams promoting will be very active and should add to the quality of JBBL.
