Is there a logic to who does not get involved?

Judges 5:15 (ESV)

15 the princes of Issachar came with Deborah, and Issachar faithful to Barak; into the valley they rushed at his heels. Among the clans of Reuben there were great searchings of heart.

Reuben and Gilead, as Transjordan tribes, did not get involved. They must have considered themselves too far away geographically.
