"Injustice League
The Injustice League takes action conservation to an entirely new level. If you have two or more Injustice League members facing a foe together, they can all attack for one action. This includes ranged attacks, as long as everyone is adjacent. Also, you are not limited to attacking just the adjacent foe with this swarm attack."

I found this description after clicking on the IL icon at the Wizkids site. What baffles me is the last sentence. I think with updated rules, the description is probably outdated. It sounds like you could be adjacent to an enemy, and then attack a nonadjacent enemy, granted you have ranged attacks. Probably should ignore that.
However, what I would like to know, after reading the updated rules section, is whether or not IL/MOE members have to be adjacent to themselves and at the same time be adjacent to an enemy, e.g.:
XXXXX
XMEMX or
XXXXX

XXXX
XMEX or
XMXX
XXXX

XXXX
XXEX
XMXX
XXMX
XXXX

X=Space, E=Enemy, M=MOE/IL

I think only the second one would work according to the updated rules' wording, but the first and third would only work if based on one-half of the wording. Thanks for any help.

MOE/IL members need to be adjacent to their target but not to each other. The Wizkids description on the team list is outdated and was wrong from day one.
